Just a comment... Going clockwise can be a bit of a challenge, weather wise. You may want to avoid being too far South in the Summer months. Same problem being too far North in the Fall/Winter. We are planning our trip out West in September and October, doing the more North sections in September and leaving for the Southern return route in October.

We are looking at Santa Fe, Grand Canyon, 4 Corners/Moab, Salt Lake City (POG rally), and then beginning our swing back South with Zion, Las Vegas, Phoenix, Las Cruces, Dallas, Little Rock, etc.

Hopefully we will minimize our chance for extreme heat or cold. We also hope to avoid the Summer school vacation kids crowds.
