After a small google, I discovered several CSA farms in my area, Here's some photos from one of them

Sounds like an interesting alternative to a farmer's market, getting a box of produce each week and then trying to figure out how to eat or preserve it. The one mention above provides 20 weeks of produce for about $400. The amount of the box depends on the harvest, but is estimated at enough to feed 2 people.
