1+ on Rushmore Cave. The Zip Line car ride billboard is what got the son's attention. :)
Badlands was SO impressive. We did the board walks at midnight under full moon since we arrived at 10 PM then we did them the next morning on way to Mt. Rushmore where we ate lunch before going on cave tour then driving over to Cody to a WM.
One thing that I did not realize before getting to the Badlands is how easy it is to drive through NP's and NF's on the way to the next key stop. We took mainly 2 lane roads to YS from Rushmore letting us experience NP's and NF's that we would have missed doing the same by interstate.
In the west taking the interstate can make for a much longer trip plus many of the two lane roads have the same speed limits and NO traffic plus you get to see and do things that would otherwise be missed.
