Lots of trees down and debris on trail. Had to venture pretty far off the path to get around some of the larger trees.

      All trees cleared. SADLY, someone blew the leaves off 100% of the trail, even on steep slopes. This is the worst thing anyone can ever do!!! Beginner trail builders working on expert trails with novice riding skills is not a formula for success. All the cool features are gone, but thanks for removing the trees, you tried... The Fall leaves and pine straw become next summer's top soil and will protect the trails from erosion better than any waterbar. if you blow the trail then you need waterbars every 20-40 feet. B+BUILD THE WATER BARS FIRST! There are no water bars, and next week is all rain and now this trail will see decades worth or erosion, more than it has ever had in it's lifetime, tanks to th guy that thought blowing the leaves off a steep slope was a good idea. Was this Clemson or just some Gumby that did this? I give the school an F for this fail. DO NOT BLOW TRAILS, ok, blow the apex of the corner if needed, but never the straight-a-ways, never. You thought you were fixing the trail, but now you ruined the trail!

      Multiple trees down. This trail needs some work.

      Kind of a drag. Not a black. If you go go clockwise you end w a quick clean straight line.
