Sure, there are places where you can get live chickens, some herbal shampoo, and an antique typewriter in one stop. But nowhere will you find it easier or more fun than at the flea market at the Memphis Drive-In. Each Saturday morning, vendors line up to offer you anything and everything you could possibly want -- and definitely do not need. Budweiser signs, old bikes, Tuna Helper. The place is like Wal-Mart for Gypsies. Be forewarned, however: It is almost impossible to escape without plunking down some cash.
