I think I may have also found that same moldy "log" a while back. If the sofa was at the Ant-Hill cache, that sofa was still up there as of last fall... not to mention about several hundred booze bottles and and cans. There also appeared to be a makeshift dwelling next to the sofa. It was dark when I hit this cache and I was on my own so I opted to not see if anyone was home. I found the cache and left quietly like I came.
