For me personally (and it's just me and my caches) I limit my caches to areas where I know I could go to and check for problems that day if need be . . . which tends to be in the city where I work and in the town (and surrounding towns) where I live.
If someone has made arrangements to have a local cacher maintain their cache if need be, I would have no problem with that fact. Again, only my opinion.
