We just returned from a short vacation to the Black Hills - towed our 178 from the St Louis area. I'm retired AF so we stayed at the 'famcamp' at Ellsworth AFB (Rapid City, SD) and from there made trips to the Bad Lands (1hr), Crazy Horse (< 1hr), Mt Rushmore (.5 hr), Custer State Park (.5hr), Devils Tower (2hr). Keystone and Deadwood were packed with tourists so we drove through, didn't stop. We traveled through SD on I90 and stopped at Wall Drug (Wall, SD), 1880 Town (Midland SD), and St Joseph college - Indian museum and cultural museum (Chamberlin, SD). Going to the Black Hills we spent a night in Sioux Falls at the KOA (well run), and on the return Omaha, NE KOA (adequate, but really packed). We particularly liked Crazy Horse (participated in the 10k Volksmarch), Bad Lands, and Devils Tower - probably make another trip out in that direction in a few years and include Yellow Stone. Best vacation I can remember. Photo is Ellsworth AFB Famcamp.
