Thanks, we have a 2017 Milepost, Church's Camping Guide and are ready to go. We have been there before but on an RV tour, just not enough time to see things. Plan to spend 3-4 months if needed. Heading up that way, very slowly, from Phoenix at the end of April.
We are goign to go up the west side of the Rockies and come back in the fall on the East side.
