East to West?

We left on 8-28 and did the northern route (basically I-90) out to Washington State. Had a couple frosty mornings in Montana the first week of Sept. Don't leave too late in the fall if you go at that time. MT. Rushmore was nice to see along with Crazy Horse Memorial. BUT, if your destination is AZ then going up there is a LONG WAY away. It all depends on how much time you have on hand. We were gone 2 months and I feel we didn't get to stay at some places we would have liked to stay longer at. Don't cut yourself short on time at any place you want to explore and enjoy. We did the southern route (I-40) back home to TN. Standing on the rim of the Grand Canyon is an awesome thing. AZ has ALOT to explore and we are going to go back there possibly next August. Pick a place to go and stay long enough to see things. Don't just be driving all the time.
