So, what is a CSA?
CSA = Community Supported Agriculture.  Essentially, it's a group of people in a given community (in this case, Sunnyside and Woodside, Queens, New York City) who come together to partner with a local farmer (Golden Earthworm Organic Farm) who provides fresh produce every week during the harvest season. 

In practical terms: the community members pay for a "share" of the farmer's produce during the season.  The payment is collected in the spring, and the farmer delivers the vegetables straight from the farm to a central pick-up point every week.  The community's members come to the pick-up point to collect their "share" of the produce- typically 6-10 different kinds of seasonal vegetables every week.

The produce is local, so resources aren't wasted in transporting it from all over the world, and there is no middle-man, so the farmer earns a fair amount for his efforts. Because our members are drawn from the community geographically, CSA membership cuts across all other common barriers like race, language, national origin, and so on, and true community is developed at weekly pickups and other CSA events.
