Produce doesn't always come from local farms, and subscribers have reported apples from Washington and peaches in May (not in season). CSAs are supposed to be built upon supporting local farms and eating seasonal produce.
The designated local pickup locations are at Davis, San Francisco, El Cerrito, Vallejo, Alameda, Emeryville, Oakland, Berkeley, San Rafael, Mill Valley, Sacramento, Vacaville, Lafayette, San Leandro, and Castro Valley.
The farm encourages building personal relationships and retaining long-time customers. Part of their reasoning in requiring minimum payment balances is to encourage customers to increase their stake in the CSA.
