Why do we take our Airstream out on the road these days?

Got an eye opener this past weekend as we drove to the southwestern part of the state, staying the night in Reeder.  We took the Enchanted Highway and saw the awesome sculptures along the way, and battled 30-40 mph direct crosswinds and rain the entire way.  Stopped for gas in Regent and noted that diesel was $4.82 a gallon.  Due to the lovely winds that did not abate the next day, we topped off gas in Belfield and was surprised that it was only $3.82 a gallon.  The eye-opener came when we were talking with our friends who had reservation at one of the  few hotels in Medora.  They got one of the last rooms available for $169 per night – the rest were $189 per night.  I sat there and did the quick math: we had, by far, the cheapest and nicest accomodations.  Is that what hotels are going for these days?!  Even with the voracious headwinds we had, we still came out way ahead on costs.  At $4+ a gallon, we can get a long way on the money for just one night’s stay in those hotels.  Our RV site was $30, with full hook-ups, WiFi and cable TV.
