The last day in the US we spent at the Lewis and Clark Campground and the manager suggested that we hike the Roadrunner Trail. We forgot that we are "flatlanders" and that we were in a more hilly terrain. The trail went into the town of Shelby, MT, and was about 5.5 miles. We walked about four miles total and that was just right. Along the trail we found several wild flowers in bloom and many rocks that were a variety of colors.
