Abandoned school around the corner from my apartment. 

Elsewhere, there are heaps and heaps of trash and empty bottles, as well as mattresses, broken furniture and a blackboard on the floor.  Everything is defaced.  To get in, I climbed through a window around back, (in the process,startling and being startled by a stray cat in the bathrooms). 

The place is probably 10 degrees cooler than outside.  I was in there at sunset, but I got the hell out before the sun actually went down. Closest I’ve ever felt to being in a horror film.
