Pi Even: I went to check on it and found a container different than I placed. It was a flimsy, disposable container. Lid was off, contents on the ground. Water in the container. Log book soggy.
Read the first page of log book and the author on July 6, 2013 decided to replace my "small, crappy" container with a larger one.
Ironic that my small tupperware container could survive the elements and the replacement could not. And the small container could be hidden, while the large one was exposed and probably muggled.
Deciding to archive, rather than replace. Sent an email to the replacer to read geocaching 101.
