I explored this abandoned Boys and Girls gym last summer, and it has since been demolished. (pics aren't the best, but the building was known to be checked by law enforcement every 2 hours, so we had to be fast).
Here's the outside. There wasn't much cover around it and the main road, so we had to be super careful.
Interior of the gym:
Notice the little piano standing in the middle of the gym floor.
Old coke machine in one of the basement rooms:
Super sweet arcade game just left behind.
Creepy. . .
Wish I could've gone through this building a few more times, but it was demolished the week after I visited
