Best ice cream, Mo"s Cones, is in Laurel Mt just outside of Billings. flew into Billings last year on the way to Great Falls just to go there. Stayed in Best Western downtown Billings just a couple of miles from the airport. The Bighorn Battlefield, Pompeys Pillar and the Petroglytfs Park are all great places to visit. In Cody the Best Western, not BW Plus, is a great little motel within walking distance of the museum. Great ride into Yellowstone, plan for a full day to get to old faithful and back. Have a great trip.
