Seems like some pretty decent trail, I would recommend taking a left at the trail head as this will bring you to some nice power line trails. It seems like there is a decent little network here, though unmarked, of double and singletrack. Parts of the trail could use some work and more traffic. All together, a decent place to ride.
Take exit 34 (Winn Street in Burlington) off 95 North. At the end of the ramp, take a left onto Winn Street and go through 3 traffic lights. After approximately half a mile, take a right onto mill street and follow for about 2-3 miles through soccermom-ville. Turn right onto Town Line Road and the trail entrance will be on your right, toward the end of the road.
