Consider joining a CSA!
A CSA (short for Community Supported Agriculture) is a nifty way for you to have a closer relationship with the food you eat by directly supporting a farm in your local area. Many farms offer produce subscriptions, where buyers receive a weekly or monthly box of vegetables, fruit, flowers, eggs, grass-fed beef, olive oil, milk, coffee...all sorts of delicious stuff. By making a financial commitment to a farm in advance, you become a member, shareholder, or subscriber of the CSA. Some CSAs also welcome (or require) members to work a small number of hours on the farm during the growing season.
There was a decent article in the NY Times today about CSAs.
Find a CSA that serves your neighborhood at Local Harvest.
And, joining a CSA is a great way to meet the 100-mile diet challenge (see Sarah White's July 8, 2008 email...thanks, Sarah!).
Feel welcome to ask me about my experience with CSAs too...I used to get produce from mariquita farms, and currently subscribe to eating with the seasons...and they're great!
