Hackberry Arizona, on route 66. The mother lode of Mother Road memorabilia, inside and out, is the Hackberry General Store/museum. There are vintage gas pumps out front (but there is no gas). Mobilgas’ Pegasus leaps from the roof, and the Greyhound dog welcomes bus travelers. Inside, visitors can walk through a vintage diner and have a bottle of Route 66 Root Beer. Virtually every trinket bearing the Route 66 theme, from neon to key chains, is in the store, and the guest book holds signatures from around the world.
