ohjoy!: I went to fix things up, and realized that the piece of log had been left upside down over time so that the area around the cache container was open to the elements and the large log piece was deteriorated as a result. Thinking about how trashy the area has become, and the danger of kids getting out of cars on the edge of a busy road made me decide to pull out the container and piece of plastic with a nail and archive the cache. The piece of log was left in place; the rest is in my trash.
