This is the hardest 'Welcome To Ararat' cache. This cache can't be reached on foot, you must have a car or motor-bike. The sign is in a cutting on the top of a hill, it can't be reached leaving Ararat (use the waypoint to turn around).
The sign is in a 100km zone, and it is hard to see traffic coming up behind you, when you are pulling out from GZ.
Park at GZ. The cache is a Bison tube, BYO pen
Look out for muggles in fast vehicles (including cattle trucks), snakes (in warmer weather), turtles, lizards and echidnas.
