knowschad: This is one of the most unusual cases of muggling I have ever experienced. I went for a ride down the bike trail that goes past this cache. As I passed, I looked over into the woods to see two burly guys hoisting the huge cast-iron relic that my cache was hidden on into a wheelbarrow! This was a piece of a railroad "truck" (or, wheel) that had been there for many years. I guess they decided to salvage it for the scrap iron.
I considered asking them to let me take my cache off first, but decided it best to just keep moving.
I have some ideas for a new cache nearby if the spot doesn't get taken first. Meanwhile... this one is gone!
