Thanks for the reactions so far!
During the 3 nights in Custer we are planning to visit Badlands, Black Mountains and (maybe) Mount Rushmore. Is Wall Drug a must see/do? I'm not sure the boys will like it. ;)
More time for Glacier means that I have to take away a day somewhere else. That will be a hard choice, maybe a night less in Custer? Or leave Jackson Hole out, but we really wanted to see Grand Teton.
Visiting Ellsworth would be through the museum and if security permits. That's why we start with Boeing, that is most of the time no problem, I was told.
OK, alt 14 it will be! I'm counting for the moose to be there... ;)
Beartooth would be nice too, will be looking for a way to fit that in.
Pfffffff, very difficult to choose, wish we had a 2 months holiday. But that won't be long enough either, I guess. :D
