After spending the night at Root 66 RV Park off an exit for Sun Valley (doesn't seem to be a town, really), a little west of the NP, I spent over 6 hours in this park seeing the Painted Desert on the north side of I-40 and then going to the south side to see the Blue Mesa, more badlands, and petrified wood. I stopped at all the pullouts and walked a few trails. One of them is a mile long and goes down onto the floor of the "canyon" inviting us to enjoy the silence there. NOT for me! I didn't want to hike back up the trail, even though it was paved the whole way, like a bike trail!
Another night at this remote campground right next to the freeway, and it's westward ho! again!
