there is so much to see out west...don't know how much time you have but i love cody with the buffalo bill museum and the street gun fight every night except sun in front of the old Irma Hotel...also a rodeo and old trail town. jackson hole (fun dinner theatre)and the grand tetons go into yellowstone from the south...out the north east entrance through the beartooth pass onto the beartooth highway (cooke city, MT) most beautiful highway in america according to charles kurault...down into red lodge and back to hwy 90 near billings....hard to see it all so choose your favorites...another great town to visit in SD is deadwood. early aug is sturgis bike rally so expect millions of bikes in the whole area...have fun! if you want to attend sturgis i recommend staying in spearfish, SD. you can camp in the city park and it is quiet, good for us seniors
they also do a Passion Play.
