I grew up on Stowell Road in Ashburnham, adjacent to the State Forest. The State Forest is huge. We rode trikes and dirt bikes all over the Forest in the late 80's and early 90's. I haven't been back since and have no idea if there is any singletrack. BUILD IT.....and never speak of it here.
In some mysterious way woods have never seemed to me to be static things. In physical terms, I move through them; yet in metaphysical ones, they seem to move through me.
