Back in May 2016, my husband and I had the opportunity to visit South Dakota for a few days. We explored Badlands National Park, the Black Hills, Mt. Rushmore, Custer State Park, and more. While the weather was still a little wintry (on the first night, the temps got down to 19°F!), we enjoyed hiking in cooler temps and the lack of crowds. Plus, we got to see bison calves!
