I also had one travel bug that has been gone for about 3 months. I did some investigating and am pretty sure that it was in a cache that was muggled or destroyed by a critter (it disappeared in Alaska). I'm not giving up hopes that it will ever be found. So far I have found 2 travel bugs that were probably dropped off in caches, but not recorded. One of them was "lost" for more than a year. Finding 2 was almost as exciting than losing one...........
