Not everyone thinks that cemeteries are appropriate locations for anything other than their intended purposes. Some feel it is sacred or hallowed ground. Others feel that the history lessons that can be learned from visiting older cemeteries outweighs those concerns. And some just want another smiley.
Just my opinion. I never cache in a cemetary if there is ANYONE around. Not concerned about muggles - I just think it is disrespectful to be playing a game when someone is there visiting a loved one's burial site. Also, I haul a vanload of kids with me caching and we are more obtrusive than most.
