Grantville, Georgia, is conducting tours for fans of the AMC television show “The Walking Dead.” The show filmed an episode in the town, which features old and decaying buildings left over from Grantville’s days as a mill town. The tours are free of charge. The town asks only that tourists “please visit Station 22 Grill, where the burgers are ‘to die’ for. Then, come back as a Zombie and have another!!”
