cachehedz: This was an odd "muggling", indeed. Both the main cache and the bonus cache were trashed, and the empty ammo box was carried .2 miles to the site of the bonus. I hope it was simply a really, really lucky muggle that stumbled onto two caches, because I don't know how else one would find the bonus without a GPSr.
Oh well, the logbooks were recovered, and I managed to find the travel bug that was in the main cache.
Thanks to all the visitors - almost all, that is [;)]
