I have only found one trackable, a geocoin, and I brought it to a few caches before putting it into another cache. The cache I put it in is at a lighthouse which can only be accessed by navigating a long line of large rock piles, so it doesn't get too many visitors due to the high terrain rating, especially when the rocks are icy. After I put the geocoin in it, somebody logged a DNF a few days later, and then a month and a half later, someone found it, but they said the geocoin was not in it. The next person to find it couldn't find the coin either. I know some cachers may not log a coin properly when they take it, or just mistake it for swag and take it, but there were no reported finds between mine and the person who didn't find the coin. Has this or something like this happened to anyone else before? I feel almost responsible for the coin going missing. It's been from Alabama to Nunavut, to name a few places.
