This would have been a perfect ride, aside from me being stupid and breaking my bike. Well, not breaking, but denting in one of the rear struts enough to make the rear disc and caliper assembly drag. $500 29er with an aluminum frame, means it is done. At least it was on the downhill in the last third of the loop.
Do not be dissuaded from heading up Bergen Peak trail, it looks rocky at the trail junction with Meadow View trail, which it is, but those are pretty much the only noticeable rocks you will encounter on the trip to the peak.
