I'm on the board of the Catholic Urban Farmers of Denver. We have two urban farms in Lakewood and Littleton, and are trying to increase the availability of nutrient dense, organic food in the area. As well as working the farms, we will be working on members yards, and doing a lot of experimentation. We have a new website, here, where we will be posting updates on our progress. Come and check it out, and watch for updates!
