Pittsburgh PA to Yellowstone National Park need some ideas
Planning a trip to Yellowstone leaving Pittsburgh on July 11th 2015 taking a 2012 Dodge Ram 1500 with a 5.7hemi and a 31 foot Forest River Salem travel trailer. I plan on making it to Rapid City South Dakota by either late Sunday night or early Monday morning and need a camp ground suggestion so that we can camp two days there to see the sights ( Mount Rushmore Deadwood Sturgis and needles highway) leave Wednesday morning stopping at Devils Tower and make the north gate of Yellowstone by Thursday morning we have reservations at Fishing Bridge campground in the park for Thursday through the following Wednesday( I read somewhere you had to be there early to get your campsite ,if you have reservations will they hold them for you or do you have a time limit to check in?) and then we want to head south through Grand Tetons to Denver arriving there Thursday morning and leaving Denver Friday morning to head back to Pittsburgh so I need campground ideas for Rapid City South Dakota and somewhere around Greeley Colorado.
I don't want to come thru Big Horn cavern with the travel trailer but how far is it from Fishing Bridge through Cody and then to the canyon because I would still like to see it. We were there in 2002 and we're just in awww of it so we want to go back
