As we head into the growing season, try to find some local farm stands. The one's around me last year had squash @ 5 for a dollar, peppers, onions, and beets out the wazoo. I found one farm stand selling meat from one of their cows, $2.00/lb ground beef, and 2lb bone in ribeye steaks for $7-8 total!

Definitely the best way to get fresh and local produce, though Big Y often carries local when in season as well.
