I live in a crack-head infested neighborhood in Detroit and they'll steal ANYTHING.  I have had good stuff stolen - floor jack, binoculers, GPS - etc.  I have had CRAP stolen - plastic (lock n lock) box, cheap knife, books, cheapo flashlight (worth a dollar), cheapie rain poncho - really - they'll break into a car for pop empties.  They don't care at all.  I rely on my reputation as not quite "right" to fend off the neighborhood regulars, but every now and then things happen.  I try to stow what I can out of sight or in places that a crack head in a hurry wouldn't look - under the folding back seat of my Cherokee, etc - but they take what they can.  I've had a full BOB taken.  Not just from home, either - I had a back pack full of books taken while playing at a bar in a crappy area years ago.  These days I try not to keep electronics or anything I'd really be sad to see gone in the car.  That stuff I keep with me in my maxped jumbo.
I've had dog tie outs stolen from my porch.  If it's not nailed down - it's fair game here.  I'm glad to hear you don't have the same problem.
