Buffalo WY to Black Hills BDR-X

Hit the interstate - Stopped at Devils Tower then took a valley road into Spearfish SD. I was planning to start the BDR-x on Stage 2 and loop back to Spearfish as it was the easiest way to head back home. Recent rain made a good portion of stage 2 quite poor. 1 unintended dismount in the mud and I was about to drop the luggage when a SxS came thru and helped me pick Dolly up. I continued and around Castle Mtn I slid off the trail over the edge. I built a gravel ramp to get the bike back onto the trail and stopped at the nearest campground for the night. Mud and trailmax mission tires dont mix
