South Dakota’s Custer State Park is home to a huge herd of bison and many amazing rock formations, including one known as the Needles Eye. To reach it, vehicles on the Needles Highway must pass through a narrow tunnel, carved into rock. It appears to be only a few inches bigger than the park’s tour buses. Some visitors from New Mexico who were towing a camper had a close call in the tunnel. Their eagerness to get through, rather than turn around and go the long way, cost them a couple of awnings.
