The Atlanta State Farmers Market is a real farmers' market. It is a major wholesale hub with semis full of produce going in and out. But it also has a number of vendors who specialize in retail. Just drive up and down the rows and you will see at least a dozen retail stands. The people who run them are always very nice and helpful.
And what a bargain. I paid a grand total of $16 for this haul: a box of Roma tomatoes, a half-dozen tomatoes, and a bunch of bananas. The tomatoes were $13, in case you were wondering. That works out to $1.30 per quart of sauce---I have a pot of sauce cooking right now.
