The legendary Wild West town of TOMBSTONE lies 22 miles south of I-10 on US-80, 67 miles southeast of Tucson. More than a century has passed since its mining heyday, but “The Town Too Tough to Die” clings to an afterlife as a tourist theme park. With its dusty streets, wooden sidewalks and swinging saloon doors, it’s barely changed. The moody gunslingers who stroll the streets these days are merely rounding up customers to watch them fight, but there’s enough genuine rivalry between groups to give the place an oddly appealing edge. The ideal time to visit is during Helldorado Days in late October, a bonanza of parades and shoot-outs, when the air is cooler and the sun less harsh.
