We are flying from St. Louis, MO to Seattle, WA on Aug 31. My son is stationed there but will be getting out of the military. We are going to make our trip back home(St. Louis area) a road trip. We plan on making the driving part (Seattle to St. Louis) in about 3 days. We would like to tent camp and at some point stay in a hotel for a nice shower and real bed. I've been thinking about going the route to see Old Faithful, Badlands, Mt. Rushmore. But what route is best at that time of year and what are some must sees? Any pointers on driving through the mountains in a Honda Accord?
Thanks in advance
