I ran the trails there for the first time last fall, with a trail group from MoCo Road Running Club, and then again with another MCRRC trail running group in December I think. At first I thought it would be a nice place for orienteering -- lovely woods and some cool rocks -- but then it turned to thick rather ugly woods. I think the size is less an issue than the lack of nice woods. Small stuff can always be used for a Summer Short Series event.
