The Highway 41 North Flea Market is located on the north side of Calhoun across from Battlefield Lumber and Supply. When I stopped by in early March there were about a dozen vendors set up. Lots of good used stuff. Furniture. Lawnmowers. Tools. DVD's and games. Some glassware, dishes and collectibles.
It is an outdoor market with only a couple of dozen tables but plenty of room for a vendor to set up his own. Tables were renting for four dollars a day but I would expect the price to rise to $5. It is in a great location. Definitely a place to check out if you are looking for a spot for The Dixie Highway Yard Sale coming in early June.
They have sausage and baloney sandwiches as well as coffee if you want breakfast.
My one complaint is the entrance. They have only a small driveway for entrance and exit.
