We transitioned into South Dakota today and towards the end of the day we pulled into the little town of Wall SD, which if you probably know is famous for Wall Drug, a unique style of business that started life as a real (and unsuccessful) drug store back in the 1930s. Unsuccessful that is until the owners decided to offer passing travelers free ice water. Today it is a massive complex of mismatched buildings selling all kinds of stuff from junky souvenirs to high end leather goods, ice cream and fast food. Since its first founding two nearby tourist attractions (Mount Rushmore and The Badlands National Park) have come into existence and one assumes they contribute significantly to the evident success of Wall Drug.
After Wall we headed a short distance south into the Badlands National Park and Sage Creek campground (primitive pit toilets and no water). The campground seemed to be popular with the local Bison as there was a herd of a couple of hundred scattered around and through the camp.
A German couple in an expedition truck (based of a Steyr) were also at the campground.
