Hoover Dam, Route 66, Williams, AZ is a unique fun little town. Their motto is where a "Cowboy dies everyday". They have a shoot out on the main drag somewhere in the town. There is a train ride to the South Rim. DS loved it. Walnut Canyon, close to Flagstaff. I think it is to the East. Fascinating cave dwellings a short walk to them. Be sure to have a Hotel reservation in Flagstaff. We like to just wander and "find" one. We almost didn't in Flagstaff, ended up at a less than desirable one but it was a bed.
