There's also a nice quarry just outside Dunsville where you turn off right to head out towards Hatfield - there's always a few out there having fun. Dunno just how good it is cuz I like to stay on the road whenever possible (except when diverting into the long grass for a quick :hump) with Rosie
), but my eldest brother used to use it almost weekly - he's a mad tvat though and likes to go in the opposite direction to everyone else to make it more difficult
