I'm late to this thread, but saw several mentions of travel to southern Utah and Arizona. If you ever go to this area bring your mountain bike. While there are some very pretty road segments in that area the mountain biking is absolutely outstanding. Since retirement I've traveled to St. George, Moab and other areas in that region several times with my MTB and loved it every time. Fun if you're hard core or even a slow timid old fart like me.
