Mt. Rushmore and Devil's Tower are not very exciting. Glacier National Park and The Grand Canyon are excellent, though. If you haven't been, I'd of course recommend Yellowstone National Park. I'd skip Mt. Rushmore and Devil's Tower for Yellowstone. Certainly check out the Redwoods in Northern California since it appears you'll be up that way. Maybe Bryce Canyon in Utah if you end up going that way...it's very pretty. Take a nice camera with you
I've been to yellowstone once, but it was only for a day. I wasn't too impressed. I saw old faithful and we drove through most of the park. I don't know if it's worth a second trip.

I saw Bryce Canyon last year, along with the Grand Canyon and Zion Nat'l Park. Go to Zion National Park for the Day. GO TO ZION. Absolutely Amazing. Climbing up to Angels landing is one of the best things I've ever done, and will Gladly do it again.
I wasn't planning on heading through Utah, but now with all you guys recommending Zion, I'm considering it. I've driven through south Utah a couple times, but I haven't actually entered any of the parks.

Hmmm. If you've never been to any caverns, might I suggest a slight detour to the south
I don't think I'll head that way, but caves are definitely looking more interesting. I think I read about some in montana, or one of the northern states

If you are going that far north, make sure to make a trip to vancouver.
I actually forgot to mention it, but it's definitely part of my plans.
And for all the route 66 fans...it doesn't seem interesting enough to extend my trip for that much just to go back and ride it. Maybe it's an integral part of the road trip experience, but I doubt I will be doing it.
