Well, I would head south across the dam. Stop at the dam for some pics and then keep going south. Hit Kingman and do the Route 66 thing taking 66 over to Seligman. Seligman is where the historic Route 66 Association started, and it she setting for the Cars movie, as in Seligman is "Radiator Springs". Summertime is obviously the best time of year for this because Seligman really puts on a show for the people stopping in.
