At the very early stages of planning my road trip this site was my first port of call and now it is all booked I thought i'd pop back and say Thank you for the advice.
Starting in LA (Riverside) I take in Sedona, Winslow, Four Corners, Monument Valley, Grand Canyon, Seligman, Kingman, Hoover Dam, Las Vegas, Death Valley, Yosemite, San Francisco and PCH back to LA.
I'll make a point of coming back in August and letting you know how it went, but really appreciate the advice given.
Thanks again
Peter
