If you have young kids take something for them to feed the burros in Custer State park. That was my grand daughters favorite thing. Also the suggestion to tour the Little Bighorn Battlefield is a good idea if you like history. Be sure and read up on the battle before you go. We took a sometimes gravel road after leaving Little Bighorn and drove over to Pryor and Edgar MT as we wended our way to the NE entrance to Yellowstone at Silvergate. Beartooth Pass is very scenic.

Patriotism (and religion) is the last refuge of a scoundrel.
