Chach Sikes


Earliest lemon memory: Submerging a lemon slice in a glass of Southern Sweet Tea. Thinking that it was amazing that you could cut part of the lemon and it would stay on the glass.

Chacha Sikes is an experience designer, technologist and community organizer who designs new civic technology to improve our local food systems. She is passionate about helping amplify the good energy in our regional food systems through innovative technologies. She was a member of the inaugural class of Code for America fellows, a "geek peace corps" in which she did projects around civic engagement for the City of Seattle. She co-founded the Iconathon and Open Food.

Chach was born in Mobile, Alabama and grew up mostly outside Boston. She grew up in a maker household (and is the oldest of three sisters), with every available space dedicated to hobbies and projects. She began programming in 1983 at age 8 because her scientist father had computers. She has always loved learning. She graduated with a B.A. '97 in cultural history from Bard College. She had many jobs in various restaurants (including baker, raw food chef/preparer) and was a worker-owner at Rainbow Grocery Co-op. She was a puppeteer for many years, and wrote, directed and costumed a fish burlesque play as part of the NYC Fringe Festival which turned her off theater forever. After reaching a crisis from anti-intellectual San Francisco art culture, she fled to the hyper-nerdy maker oasis that is the Exploratorium, where she was a multimedia exhibit designer/developer for 4 years and worked on hybrid online/offline experiences to bring Exhibition experiences to homes. She was very involved with Drupal for many years, until joining Code for America and working more directly with cities and communities to give more power and voice to how we live together and make our cities more liveable and healthy for all of us.

Booka Alon

Lemon Ambassador

Earliest lemon memory: eating lemon poppyseed sponge cake that my Mom used to make. Realizing that lemons are magical when my mom squeezed their juice all over apples to keep the apples from turning brown.

Booka was born and raised in St. Louis, where her she grew up watching her mother propagate new cultivars of African violets during her early childhood, and prepare fresh, seasonal meals for the family. Her father, an architect, had a major impact on her exploration of urban design and civic planning. After graduating with a Bachelor of Science in Political Science from Kenyon College, she lived in the Netherlands for a short while, before returning to St. Louis to begin her own jewelry design business, operating her own shop and managing the online store for four years.

Once moving to the Bay Area in 2006, she sought out ways to blend her appreciation for food, passion for social justice and natural skills as an entrepreneur. As a volunteer coordinator for San Francisco's own Slow Food Nation event, which drew half a million people, she became invested in the Slow Food Movement. She was asked to join Slow Food Berkeley, as Treasurer of the Board and served a year in this role. She was the Operations Director for Oakland's first Eat Real Festival in 2009. In 2010 she turned her attention from slow food to slow farming. While enrolled in an urban permaculture course, she helped activate the Hayes Valley Farm Project, where she continues to lead community events and fundraising initiatives that highlight simple strategies for growing your own food. She currently teaches staff and patients at the Veterans Administration Medical Center of San Francisco, as part of a Kitchen GardenSF workshop series. She also teaches youth programs at local elementary schools in Potrero Hill. Booka currently lives in the Haight, where she nurtures her own small backyard crops. In 2011 she founded the tree-advocacy organization, Roots to Fruits, to support the planting of fruit trees in Bay Area schools and open spaces. In 2012, she joined the team to help launch Just One Tree., an organization dedicated to promoting greater urban self reliance through orchard tree awareness and education.

Lemonopoly is free to play. You do not need to own a lemon tree to play. You can play by walking your dog and being creative.

Lemonopoly is a game for all ages.

To JOIN, simply sign in through Facebook. Join a team for your city and neighborhood.

To PLAY, select a challenge. Do the challenge. Take pictures to prove it. Submit your evidence.

Play in your neighborhood near your home. Play with your friends and co-workers.

The main Lemonopoly cities are currently San Jose, San Francisco, Oakland and Berkeley.

If you live somewhere else, we will add that city after more than 50 people sign up to play in a city. We are keeping the game small since it our software is still very new.

Lemonopoly launches September 14, 2012 in San Jose, followed by San Francisco, Oakland and Berkeley shortly afterwards.

Lemonopoly runs through the Winter 2013. After that, we may take a pause and then run Lemonopoly again next year.

Lemonopoly is a slow game, which takes into account the natural habits of Lemons.


Come pick Lemons in San Jose September 9, 2012 10 a.m.

Lemonopoly and Village Harvest are co-organizing a Lemon Harvest. We will collect lemons for the ZERO1 Biennial from homes near Downtown San Jose. We have a few spots open. Will be a really fun morning! Sign up on Facebook

Your Bay Area City has the change to become The Big Lemon

Known throughout the world for the high culture, lemon ubiquity, and style -- a city of the Bay Area will become "THE BIG LEMON." . As you take on new leadership roles in the New Lemonopolis, your lands will earn points -- pushing your city and neighborhood towards this golden honor.

Meet the Current Cities in the running

San Jose

A sunny city in Silicon Valley - there are many homes with lemon trees that can produce up to 300 pounds of lemons per year. These fertile, moist soils were once the fruit-producing capital of the whole world, all before technology moved in. Many orchards still remain, and San Jose is home to Village Harvest, which already picks 25,000 pounds of lemons per years to give to food banks, giving much needed fresh produce to those in need.


A sunny city in the East Bay. Boasts "FRUIT"vale, which has historically produced fruit and many fruit trees remain. Temescal is known as the 'Urban Agriculture Capital of the United States.' Oakland is now the creative culture center of the Bay Area, with many thriving arts and intense generative energy. Anyone in Oakland will tell you that they are going to win Lemonopoly.

San Francisco

An international city known for arts and culture. The (real) Department of Public Works estimates that there may be as many as 4,000 lemon trees. With so many tech startups emerging, the whole world may know about these lemons trees before the other cities even start playing. San Francisco has the most public data about lemon trees. And urban agriculture is a city priority. Oh, and they have Just One Tree, a whole organization dedicated to making San Francisco sustainable in lemons.


This hippie enclave is full of thought leaders and motivated university students -- oh and a lot of low and middle income people that everyone seems to forget about. To Berkeley residents, the promise of the lemon was something they might tell you they invented. Their mature trees already supply dinner lemons for the whole neighborhood. Oh, and did you know it's totally legal to sell lemons out of your yard?

Other Cities

Other cities will be added as residents make noise. Get 50 people together and we will add your city to Lemonopoly. This is a new game, so please bear with us.

No Matter Who Wins

You will help build a grand society of lemons in our fair Bay Area. No more will we import lemons from afar. No more will we rely on distant farmers in distant lands shipping us lemons when we already have abundant yields from our fertile lands. We will plant our own orchards on our own tracts of land. We will ensure that our free lands can supply those without land with these golden aromatic spheres. We will celebrate the delicious taste of our own fruits. We will cultivate our Lemon Culture to become internationally renowned the Citrus Annals of the World.

Lemon Trees in the Bay Area

Lemon Trees really are everywhere in the Bay Area. We are making a public map combining tree data for the following kinds of trees: city-owned, visible-from-the-street, and private trees (not visible from the street) that choose to share this information.

The purpose of the map is to make our tree resources known, so that we know how many more lemon trees to plant to achieve lemon sustainability, as well as knowing how many trees are sharing extra fruits

It is fine if several people map the same tree. A tree on the map does not mean the tree has fruit (yet), or that is shared, but it might be.

Caretakers of trees in private locations may map their tree if they so choose, and you have the option to say that your tree is private and shared for general information purposes only. Citizens who see a lemon tree in someone else's yard may map a tree that they see, but should indicate that this is not actually your tree.

You will have the option to share your tree information with organizations in your city that support gleaning and city tree data. We have designed the information in a way that it will blend well with most tree mapping systems, so that your data will have a longer shelf-life.

Lemonopoly is in Public Beta

Dear Lemonipolitian,
      We are so happy that you want to play Lemonopoly. Please know that development on this game began in April of 2012, and then more in earnest in June 2012. So this is very new. We have worked quite hard to develop the interface for the game, and some basic features for you to make claims, and keep track of challenges that you would like to do.
      We launched the game September 1, 2012. We hope that you do not experience erratic site behaviors, unusual user experience, or loss of information - but this cannot be guaranteed. We do have occasional hack sessions to fix the game, and if you are particularly good at javascript, css, html, node or mongo -- please tell us. This is a civic game -- which means it is for all of us to play together. That's a big challenge!!
      If you do notice something weird (and you may), we urge to you tell us by telling us through the Feedback mechanism. We will make improvements as we are able.
      The Lemonocrats
