Unfortunately there is a chance i lost it: I have been hiking at Grand Canyon, and stayed at Phanthom ranch. There accidentally I discovered a cache and feeling quilty I kept this bug so long I hidden into it. (It was definitely a cache - with log ) however now back at civilization I realize that I cannot find that as a cache, and to make things worse I feel that the names were full names and not aliases not to mention lack of official geocache logo. So it might be gone.
On the other hand that cache is discovered every 1-2 week so there is still chance. If only I know what that was if not (geo)cache.
