I went to this area the other day to replace my muggled "Out Here It's Not Always Friday" cache with the intention of hiding a micro by a large nearby tree. As I walked around I noticed some evidence of muggle activity in the area so I walked a little further into this wooded area and came across what looked like the foundation of an old building. Walking up to the stone wall, I saw a sight that I couldn't believe... a very old, rusted upside down car. I couldn't believe it! How on earth did that end up there in that position? Well, the area just begged for a cache so I left one.
You're looking for a small camoed Lock and Lock container located right along the top of the wall. There is no need to go down to the car to find the cache. There are some geocaching glass marble like things and other trinkets for FTF.
Please note, as mentioned in one of the logs, you do not need to move any rocks to access the cache. I know most of them are cemented in place, but let's keep this nice location intact by respecting the structure.
