I have passed this location several times, and I finally had time to stop and investigate. I love abandoned structures, and this one does not disappoint. You can drive right up to GZ, but you may have to back out. If it has rained recently, I recommend parking a little ways away and walking in. I highly recommend approaching from the west side; the road becomes increasingly more forlorn and it's like something out of a movie.
Cache is a small camoed plastic jar. Congrats to fishersfinders on FTF!
