My family has done a lot of traveling internationally but we have never taken the all American vacation of a road trip out west. We live near Pittsburgh Pennsylvania and have two weeks. Obviously want to drive a different way there and back. Thought I saw a map recently on here with great must see sights but I can't seem to find it now. What attractions should we not skip. The list of attractions we have so far; Chicago, Mt. Rushmore, Yellowstone (Old Faithful), and the Grand Canyon. Suggestions and tips would be greatly appreciated.
