There's an abandoned building on Ten Rod Road, that I've been told used to be a nursing home.
For reference, it's near Fillipou's Pizza and that "King's Food Mart" convenience store.
I'm not sure how interesting it would be inside, it's got one of those temporary "wood 'n wire" fences around it, so it may have been cleaned out already. But it seems to be of a pretty good size... there's a lot of additions onto the back. It's worth a try, no?
I originally was interested in this place for the roof- but the problem with that, and with going in, is that it's on a fairly busy road, and you'd most likely be seen. (there isn't much vegetation in the back, either.)
So I dunno. It's out there, I guess, if you've got nothing to do some afternoon.
