We were vacationing in Florida last week and on one of our caching jaunts encountered a weird container. It was a huge plastic hollow bug...kind of a giant roach, hanging between two floor joists under a ranger station...elevated for flooding so we could walk right underneath. It was attached to the floorboards with a plastic ring so it could just be slid up over the beam and sideways so to access the log but anyone walking under there couldn't see it. Neat one!
