There was mysterious a flapping sound coming from the front left of my car. I figured it was a branch caught in the wheel. Stopped in a residential area to take a look at it, but I didn't see any branches in there. Then just as mysteriously, the noise went away.
It seems that there was a bit of geocache sabotage at "When a good mine goes bad." When I got there, I saw the cache sitting out in the open. The specially-constructed hiding spot was also exposed. I'm not exactly comfortable with this type of cache hide. It seems unlikely that it could have been placed in such a way without digging an appropriately-sized hole, so technically, it could be considered a buried cache, which is against guidelines.
