There is a tiny little "unofficial" farmers market that meets on Tuesdays 4:30-7:00pm...located at the corner of Black and E Short (right across from Beall Park). There is a farmer there that brings raw milk, but you need to be on her "list". She is running short right now...but it would be worth their time to just come and talk to her. There is one other guy in town who has it, but I've heard he's not always that reliable as far as organic goes.
Hope that helps!
