In August 2011 we took a trip to the Upper Midwest. On this trip Kate and I collected the final states to have visited all 50 United States. I just needed North Dakota, while Kate needed Michigan, Wisconsin, Minnesota, and North Dakota. After this trip, Aurora has been to 27 of the 50 States. This video is from August 10, 2011. We were in the South Unit of Theodore Roosevelt National Park, North Dakota driving around the park when we came upon this lone bison walking on the road.
