One Man and His Dawg: After a message from a recent 'finder' who had been unable to locate the cache container I popped in to take a look.
Unfortunately, it seems that somebody has removed the container - it's original location could be easily spotted (if you know what you're looking for) and a few small items from inside the container were found in the immediate vicinity.
Due to the location and nature of the hide, it is unlikely that it was discovered by a passerby so my guess is that it was removed by a previous finder - something which has happened to another of my caches and also to other cachers who I have chatted with in the past.
I will not be replacing the cache as it wasn't getting a lot of finds and because there is someone out there who sees fit to remove caches for their own petty reasons.
