RE: Retirement roadtrip 2013 (Glacier, Rushmore, Yellowstone)
Ditto on Custer State Park. Fabulous views and wildlife. Buffalo roamed our campground grazing all day one day. Tour the park one day, then visit Mt. Rushmore in the morning, then spend afternoon in Hill City getting to the Alpine Inn early for a great Filet Mignon dinner at a rediculously low price.
