Met my brother in Edmonton last year.
Did Jasper, Banff, Glacier National Park (states) and the Road to the Sun, through Yellowstone to Jackson hole, back through the other side of Yellowstone, Bear Tooth Pass, Custer State Park, Badlands, Mt. Rushmore, Crazy Horse Mountain, Field of Dreams.
An unbelievable trip and experience. Took 8 days though and that was in high gear.
I would highly recommend any of these and would be glad to supply extra info if interested.
