Please be careful when approaching the GZ (Ground Zero for you newbies). It is located in the bend of an S-curve. You may want to study the map before heading out. It is a bad idea to drive down this road while looking at your GPS.
There is a paved drive to pull safety off the road and park. Unfortunately, to leave you will have to back out onto the road. Please use caution. I would advise you to stay on the pavement. The ground can be very soft and the ditches are unforgiving. I have seen several cars (and trucks) stuck in the mud or in the ditch over the years.
The cache is located a safe distance from the road only a few steps from where you will park.
