Responsible rider looking for spots to ride in and around pittsburgh area. I've heard of alot of spots here on thumpertalk, just don't know where to enter the trailheads. Greenmans tunnel, monaca/center township, rennerdale, murrysville/delmont, tarentum, west mifflin. I live in the east, churchill, near monroeville. Thanks in advance for any info. Please pm me if you want. Thanks, Ron.
