I've been seeing a lot of so called 'urban caches' recently. So many, in fact, that they are becoming routine. For the most part, these are fun, but a couple of versions make me uncomfortable.
Examples are the fake electrical outlets, and fake switch plate covers
Sometimes, the actual cache IS the fake electrical outlet, or the switch plate cover, but I've been seeing quite a few caches where the real item nearby has been either forcibly busted open or has been opened with a screwdriver and just left hanging there, by someone in search of the cache. Maybe not always cachers, there are still enough run of the mill vandals out there, but you see my point.
By far the worst one is the magnetic "Danger" signs. There is a reason some things are marked dangerous, and by having some of the signs out there as caches is just asking for somebody to go poking around where there is really a hazard.
Maybe I'm just being paranoid, but I can see the potential for somebody getting seriously injured, if not killed, by taking chances with what "maybe is", and "maybe isn't" the cache.
