My wife and I are planing a national parks trip in July. We will be flying into Kalispell, MT and driving our way through Montana, Wyoming, South and North Dakota. We will depart for home from Bismark, ND. We already have reservations in the Glacier and Yellowstone/ Grand Teton NP areas. From Yellowstone we plan to drive to Jackson and Casper, WY, the Mammoth Site, Wind Cave (or perhaps Jewell), Custer, Mt. Rushmore, Wall, Badlands, Minuteman II Missle Site, Deadwood and Theo Roosevelt NP. What I'm struggling with is how much time should I allocate for each attraction. My departure flight has not been set so I'm flexible. My current thinking is 5 days. Do you think that's sufficient? Did I miss anything? I've done some reading on Crazy Horse and have pretty much decided to skip it.
