I have heard from a lot of people that Custer State Park is not as impressive as Yellowstone and is actually a let down. I am planning on staying in Custer, South Dakota and going to Custer State Park but now I am not sure. I also heard that Wind Cave was not worth going to? We are planning on going to Jewel Cave but someone posted something about their elevators not working? Our trip is fast approaching and I want to have everything figured out.
