No, the lister is a ****stick, and I promptly emailed him telling him that it's hush-hush.
Either way, it's not as awesome as you think it is. Just google map the address,
965 North Brighton Circle West
Crystal Lake, IL 60012
and do a satellite shot. You'll notice that leading from one of the parking lots is a dirt trail, but once again, it's private property, and not legal.
