I went to a cache site this week and the cache had definately gone, The remains of the box were in pieces as it had been mown when the verges got cut. I logged a needs maintenace log on the cache page and noticed that someone before me had mentioned it was missing on the 5th July, I have emailed the cache owner but if I don't get a reply should I post a sba log?

Also on the same day one of the caches I did was hidden in a small hole in a stone wall (not dry stone) the clue says "on the wall" and previous caches have obviously been lifting every lose stone to try and find it (it is very hard to spot), I personaly think this wall is being damaged by caches, Should I email the owners stating my concerns or would I be interfering and should mind my own?
