It has been a long time since this TB was placed in this cache. It is time to either forget about it or replace it yourself.
Sorry, I now that sounds a little harsh, but some cachers still go out looking for it and end up disappointed.
The cache it was in is still in place, but not for long. It has not been maintained at all since it's placement. The hider was an elementary school student who is no longer caching. The program where they learned to cache is long over. Some of the caches they placed are still around, but unfortunately in very poor condition.
I usually reissue my lost TBs with the duplicate dog tag that comes with it. Or if I can't chance loosing that one, I will make my own tag with the TB # written in permanent marker (I don't have an engraver, but that would also work!).
Good Luck and sorry for the bad news,
