Thanks, Wabbit. I couldn't get a good signal for maps and my road atlas is going in the trash. Looks like I might make Phoenix before rush hour.
Seen all of Flagstaff streets I care for.
Or you could take the scenic back roads going east from Camp Verde, to Payson, on to Globe then down to Oro Valley and Tucson. Nice drive, no traffic, no Phx. Gas up first though.
