On the third day of the trip, I started the day with one tremendous view and ended with a second. The first view was of a natural wonder of the world—The Grand Canyon. The second view was of an engineering marvel, The Hoover Dam.

On previous visit—a flight to Las Vegas—I toured the Hoover Dam and powerhouse. On that trip, there was also a convention of sorts. In the parking lot next to the spillway on the Arizona side, there was a car show—of vehicles inspired by the Mad Max movies.

On that visit, the Mike O’Callaghan-Pat Tillman Memorial Bridge had just started construction.  This picture is from that now completed bridge.
