Number one, the museum is free. The park ranger are friendly and though their is a security checkpoint, it is fairly unobtrusive and they are only looking to ensure no one has a firearm or large knife. The museum itself is loaded with great exhibits regarding westward exploration, but can be slightly overwhelming due to how much is displayed and the large numbers of people coming through at any time. I would definitely recommend stopping by if you are in the area. I skipped the $20 ride to the top.
