The weather was misty/foggy/nasty, so we decided to do our bike adventure this day instead. We rode from the Hill City Trailhead to the Mystic Trailhead on the George S. Mickelson Trail in South Dakota. 14.6 miles each way, putting it at pretty much 30 miles! It was tough, but satisfying! Don't think my butt wants to sit on a mountain bike again for awhile, though...
