Congratulations. The kids will remember the trip for the rest of their lives. We were there last year and it is sure a great area to visit.
We were fortunate that we have been motorhomers for a long time (first one in 1979 and continuous since then). My kids have seen a lot of the sights in the West and it was always neat for them (now 34 and 38) to say that they had BEEN THERE when an area or historical point of interest was discussed in school.
