Lots of Skyline drives... with the August mention, I assume you mean Skylin Drive in Rapid City?
I've been there, it's kinda cool, lots of twisty turns but it's real short. Honestly it's nothing compared to Iron Mountain!
Weather in August will be Hot, Dry, Wet, Hail, Windy, Calm, basically prepare for anything
