Camp Tuscazoar Centennial Challenge. Should have been able to do this considerably faster, but didn't take water and needed to make a very costly (time, distance, steep climb) return to vehicle after about 3 hours. Very physical course. Fun.
River had finally gotten low enough to reach all controls, although the bottomlands were pretty muddy in places. There was one control where my intended route didn't work because of high water (I won't give it away), but the control itself was accessible.
Very open forest, a few patches of multiflora rose, but they generally were not too difficult to avoid.
Biggest complaint - Some of the controls are not very accurately marked on the map; probably spent a total of 20-30 minutes circling marked locations trying to find the plaque - it was a bit frustrating when they were marked on the opposite side of a trail, building, campsite, or other object.
I didn't take a compass; it might have been helpful in the central part of camp with the dense maze of intersecting trails and rides.
Very busy park, but a lot of room to spread out. Lots of fresh tracks of hikers, horses and bikes. Saw a few mountain bikers and a couple trail runners.
