This place is truly a wreck!! Those newspapers/magazines on the floor bring back memory of a shack my brothers and sisters and I discovered near our house. This was deep in the woods. No windows. One room. A true shack. But all across the floor, like a rug, there were comic books. Some in great shape. We grabbed the ones that were in decent shape and took them back to our house. I had just finished the fourth grade and I read them over the summer.
That wasn't urban exploring. It was forest exploring :))
That sounds like a rockin' place. Exploring, before it had a name. I did similar when young, made a house our own, filled with stuff like they had just taken off. The coal shute was the way it, until we found the keys inside, then it was the back door. Happy times!
