Most people buy postcards when visiting a historic property.
They bought the property. Well at least part of it, from a developer who planned to build houses on one of the most significant sites of the Lewis and Clark Expedition. This camp was critical to the success of the expedition as it was used both before and after the perilous trek through the Bitterroot Mountains. The site, on the National Trust's 1999 Eleven Most Endangered Historic Places list, is threatened by residential development. As the Kulbergs boarded the bus after the tour, they told the guide they would buy an endangered part of the site.
