The same bad guys, sheriffs, and deputies who battle every morning near the Grand Canyon Railway Depot shoot at one another all over again at 7pm on summer nights in downtown Williams (a high school band usually plays before the show starts). The free spectacle, which moves to a different block of Route 66 each night, entertains thousands of visitors every year. If you're in town, don't miss it. These guys act like real gunslingers, only they're funny. To find out where the show will be on a given night, consult one of the schedules available at the Williams Visitor Information Center (tel. 800/863-0546 or 928/635-4061), or ask at any of the town's businesses.
