Head to the co-ordinates and let the multi lead you around to the cache, don't be surprised if you are going in circles! There are several stages to the cache, all the stages are in the same general area of the city, but require traveling some distance by vehicle of your choosing.
The first few stages are fairly easy drive up style. The final stage is a little more involved for terrain, quite uneven and rubber boots would be suggested in most seasons. Be warned that some find this cache a torturous frustration.
