I have placed and found many cemetery caches, all of which have been in good taste and not disrespectful to the departed. Cemetery caches provide a chance to appreciate our past and this should not be denied. Some cemeteries in our area have large signs saying "No trespassing except for cemetery purposes," and I will not place caches there. Most cemeteries, though, have no such signs and it is left to the cache owner's discretion about cache placement. For my cemetery caches, I always place the cache well away from the grave markers as I think that this is more respectful. I cannot see forbidding the placement of caches in cemeteries, but there should be respect for such considerations as nearness to the gravestones and the keeping of proper caching hours. If the sign says "dawn to dusk," respect that.
