Great way to get outside and get something local.
The King's Drive Farmer's Market has a lot of your regular produce items: peppers, tomatoes, fresh green beans, potatoes, etc I don't know that I can say i noticed anything really 'unique' there. But if you want local produce that will stock your fridge then this is a good location. They also have grass feed meat, pastries, and other local goodies.
Everyone seemed kind and helpful, and I parked in the gravel lot on the side of the market, there are parking attendants to help get everyone in and out safe and quickly.
I did stop by the 'grass feed' meat guy and got a huge fatty brisket, he was very informative about where the meat came from and how to prepare it more than one way.
If you're nearby during market hours stop by and have a taste!
