Some Odds and Ends that May Be of Use
Welcome aboard the RoadTrip America Forums!
1) For camping on the way north from San Francisco, that will depend on whether you take I-5 or the coast highway. I'd recommend the scenery of the later which would put you on the southern coast of Oregon by evening. There are a few state parks with camping: Harris Beach outside Brookings, Hunting Mountain and Cape Blanco south and north of Port Orford, Bullards Beach at Brandon, and Sunset Bay at Coos Bay; but if you can put down some miles you might be able to get as far as Oregon Dunes National Recreation Area.
2) The two images that stick in my mind from Glacier National Park are the views from Going to the Sun Road and those looking southwest across St Mary Lake. But be sure to take the time to hike into one of the glaciers of the park. It's likely that they'll all be gone within your lifetime.
3) Although your map shows you jogging up to North Dakota just before entering Minnesota, I think you'd be better served by leaving Yellowstone via US-212, the Beartooth Highway, and using I-94 to head east to one of North Dakota's hidden treasures. Theodore Roosevelt National Park. You would then head south to Mount Rushmore, the Badlands, Wall Drug, etc. as you continue on I-90.
4) For lots more ideas on what to see along the way, check out a couple of compilations that we've done for just such wandering trips: one organized by highways and one organized by states.
