My friend and I are planning on going on a road trip on our motorcycles this spring we don't have much time only 9 days. We are starting from western PA right about the pittsburgh area. We were wanting to go out to yellowstone and loop down to Wyoming and stop a few places there. I would really appreciate any other places we could stop like Mt. Rushmore or Crazy Horse first trip out west and we would like to make it a fun one. Any suggetions would be greatly appreciated.
