We spent a night in Rugby, North Dakota because this town is considered by many to be the geographically center of North America. We have been coast to coast and now we have hit the center point too! The strange monument Deb is seen beside is supposed to represent the northern lights. It was much too light at night during our trip to see any northern lights. We noted many nights that even at 2 or 3 am it was very light despite being in some very remote places. I'm not sure if this was due to the time of year or the fact that we travelled during the period just before and after the full moon.
