Mount Rushmore is one of the 'monumental' places that is a must-see sometime in your life. Now was our time. So on our drive across the country, we went.
There is an impressive walkway featuring flags from each of the states as you approach the monument.
In the museum, they had a dynamite plunger switch that was integrated with the TV so you could help explode the rock and see how the monument was created. The kids loved it.
We stayed at the Howard Johnson in Rapid City, SD near Mount Rushmore and they had this huge chair that the kids loved to climb on.
