Named for the man who gave me the bright green bison tube you are looking for. It is not on or beyond the fence. You may need to bring your TOTT to help grab the thread. You can park in a drive just west of the GZ or across the bridge to the east on the north side. This is a busy intersection, so use stealth, or try to look like you know what you are doing.
