I rode, or rather attempted to ride, this trail in July 2013. I started at Stockbridge. I have a 1995 Schwinn hybrid bicycle with 700 X 35C tires - typically well suited to a crushed limestone trail. The problem is that this trail has been destroyed by inconsiderate horse riders. Horse hooves have ruined the trail from Stockbridge to a point just west of Pinckney. I rode from Stockbridge east three miles, then turned around after a teeth-jarring ride over the hopelessly pitted and bumpy journey. I attempted to ride the trail from Gregory toward Pinckney, and again the trail was in terrible shape due to horses. The only portion of the trail which can be ridden on a bicycle is from just west of the Pinckney depot to the east end in Hamburg Township. This portion of the trail is very nice. It's unfortunate that the horse riders, who think they own the trail, have been allowed to destroy what could be a fine asset for the area. Horses should be ridden in the grass along the trail, and not on the improved surface.
