Route 66
There is a lot in AZ that you can run, last trip I took we took an old spur west bound from Flagstaff, Burma Shave Signs and ran 45 miles an hour for around an hour. Had a great time, you have to stop Seligman AZ, Snow Cap, order a Burger and tell them you want mustard! Be prepared to have a great time! Angel is right next door, AZ Mayor of RT 66.
