Bob, there's a really cool road thru a Nat'l forest by Rushmore, with tunnels and tight rocks. I came around a curve and cars were stopped and I thought it was the end of the road . Then I saw cars were taking turns from both sides, going between two huge boulders on either side of the road. When you go thru one of the tunnels, you look straight at the Rushmore faces. I can't remember the name of the road but some locals should be able to get you there. Craig
