Help with traveling the Beartooth Highway

Thanks, everyone! We're all set! We called the Ponderosa Campground, and they initially said there were no vacancies. But that was because they didn't want to break up the days around July 4th. So we extended our stay there by a couple of days, which allowed us to reserve there. Thanks for all of your advice. It really helped! All of the other places you've recommended will be put in my file for future reference. This summer while we're there, we'll look at the locations of the other campgrounds to consider for future trips. Now that I'm retiring we'll be making many trips out that way as we go to visit our daughter in Alberta, CA.
