Jan,
If you come up through Monument Valley, I recommend you decide your stops and get reservations. We were down at Goulding's in Monument Valley yesterday, and it looked full, the park we are in at Bluff has had a lot of traffic, and we will spend next week in Blanding, who also advised us reservations are important. If you like to boondock, well, you're good...it's not like there is not a lot of open space... 8)
We are seeing a lot of RV traffic because the weather has been pretty decent, notwithstanding the winds.
Looking forward to meeting you in Moab.
Kim
