In 90% of cases I agree, archived caches should go and a new one placed. However, I became interested in this as a very old cache suddenly turned up and was found. It is probably the oldest cache on Dartmoor and I would like to see it preserved. Several cachers have now logged it as found but I would like to see the owner unarchived it, which is allowed.
I notice that the cache on Heltor Rock has now been archived. I support this only because the CO had a stupid statement in the listing saying that if you couldn’t find it log it as a virtual, which several have! But, I bet that this cache is still there as it was really well hidden when I found it last year.
