We found a cache today that had not been found since 2011. Usually, this kind of search ends up being a DNF for us, but we still try to check them, as there aren't that many caches available in Trinidad anyway. This one was exactly where it had been left, a 4 inch tube covered in camo tape. When we retrieved it, however, a lot of ants started crawling out of it (good thing we had gloves on). On closer inspection (once we'd dropped it on the grass), we realised the ants had nested on parts of the camo tape that had become loose, and they were trying to recover their eggs from it. So, we had to remove the camo tape and let them have their eggs and let us keep the cache, or we wouldn't even have been able to pick it up and put it back on the tree if we hadn't. Now, we didn't have any camo tape with us, so we brought the cache home to repair it. Also, the container seemed to have leaked and it was filled with water, so I have contacted the owner to see if he would like us to replace it before we put it back.
My question is: did we do the right thing removing the cache? Nobody had been to look for it since 2011, so I don't think a week will make a big difference, but maybe we went again the rules, and if so, I'd like to know it so we don't do it again. Also, when I filled the log I explained we have removed the cache, but should I do something else in order to avoid anybody going there to look for a cache that is not in its place?
Thanks for your help!
