We will be staying in Story WY this October for 3 days. (Sat sun Monday) we plan on flying into billings Montana earlier in the week like Tuesday. We've never been out west so if we're that close to Yellowstone we want to go. Any suggestions on travel ? Would like to also see Mount Rushmore and the devils tower. We do not intend to spend much time seeing Mount Rushmore or The devils tower....maybe an hour at most at each. Haven't done much research on airports but willing to fly into a different one to accommodate what we want to see. ( even in its in SD or CO.) Interested in the most scenic drives as well. Any advice or suggestions appreciated! Also which route thru the big horn mountains is more scenic ??? 14 or 16?
