After leaving the Grand Canyon we took random roads to Mojave National Preserve. We do not travel with good road maps so we often travel by suggestions from locals. We have not yet been led astray. We enjoyed a couple of days in Flagstaff, Arizona, which has great coffee shops and an eclectic used bookstore to get lost in for an afternoon. Driving historic Route 66 brought us a few surprises, most adorably the wild burros and the cutsy but touristy town of Oatman.
The randomness of travel is addictive.
We definitely like to keep our plans to a minimum and let curiosity pull us.
