Every year, I buy a farm share. My farmer gets his money for the year up front; he doesn't have to borrow from the bank and he doesn't have to worry about losing the farm if it's a bad harvest. He gets to focus on growing stuff.
In exchange, every week during the growing season, I get 3/4's of a bushel of just-picked vegetables. Some are rare heirloom varieties you generally don't see; some are items you don't see much of at all; and everything is fresh and lasts much longer than store-bought would've.
