Xira: The cache has been problematic. The cache got muggled at the original location twice. So, then, in winter, I moved the cache to a new location. But the problems continued.
Today I went out to see what was going on. The first problem was that I couldn't find the first tag, even though there were no complaints about it. It has disappeared before. This time, I think it may be on the down side of the nearby fallen tree. The rest of the tags were right where they should be.
Then I went to find the cache. Well, that was quite the bushwhack, quite different from winter. So I decided on plan B. Time to archive this cache. It, and all tags, have been removed.
