Our original plan had us taking I-40 from outside Los Angeles to Memphis, but our Las Vegas detour meant we had to take the back roads to Kingman, AZ before picking up I-40. What I hadn't realized is that our route took us right over the Hoover Dam. I knew we were nearby and I had originally wanted to stop, when I thought we might leave L.A. at an early hour and get in and out of Vegas before nightfall. We were a couple miles out of Vegas before I realized the road went overtop of the dam. Naturally, we stopped for a few photos before continuing on our way to Williams to sleep.
