What Rain Does to Your Grip on Needles Highway

The video covers Needles Highway in Custer State Park, South Dakota, including the Needles Eye Tunnel. It shows the tight granite corridors, the famous needle opening, the drop-offs beside the pavement, and what rain does to grip on smooth rock. It walks through tourist driving mistakes in the tunnel and on the wet curves right after — slow, narrow, no room to fix a slide.
