I don't hate LPC hides at all. I enjoy finding them, and I enjoy knowing they're there. I like finding a cache under a lamp, signing it, and passing by it everday after that and seeing all the people walking by not knowing the treasure that's so close. I think that's kind of the joy of urban caching.
As for the whole safety issue.. I think it's really a non-issue. I've never lifted one of those skirts and found exposed wiring. If you did, the whole light post would probably fry you as soon as you touched the outside of it anyway! And the threat of bees and wasp and bugs and spiders.. Ok, like you're more likely to find these creatures under a lamp skirt than in a tree or the woods?
You can have your preference to easy or hard caches. LPC's or ammo cans. Or whatever else.. When it comes down to it, whatever you think is fun, go for it!
..Oh, and I have to say it just one more time.. Don't you guys find joy out of seeing people walk past a cache that you've found that's so simple to get to... and they have absolutely no idea?! That's the whole thing i love about geocaching.
