Ozz, Glacier National Park is spectacular. We've been there several times in the last few years (taking company to see the sights). I will warn you, however, that trafficfrom June through mid-August on the Going to the Sun road is frequently bumper-to-bumper, literally. The bright side of that situation is that you are going so slowly that you can get excellent photos of the wildlife--lots of it. And you can get a good look at the scenery.
I highly recommend the Bear Tooth Highway, too, which is close to Yellowstone National Park. The scenery is breathtaking (so is the highway):

Steve and Vicki, any chance your travels will take you to Seven Feathers for the rally in early June?
Ozz, we only had three weeks to spend on the Oregon coast when we were out that way two years ago, but we could easily have spent 2 months there. So much to do, so many beautiful sights--one of our best trips ever.
Planning is fun, isn't it!
