I was a teenager. We were in a somewhat rural area just outside of the DFW, TX area. There was an abandoned housing development that became an urban legend called "Crazymans". The area had nothing but paved streets and a large tower in the center that kind of looked like a fake lighthouse or clocktower. Supposedly the developer lost all his money and murdered his wife at the tower or something like that. Kids would climb to the top and carve their names in the wood, drink and smoke, etc. The ladder was on the outside and it was somewhere around 3-4 stories high I would guess. It was the middle of the night and I was the first one in the group to go up. As I reached the top rung on the ladder a huge owl flew out and scared the shit out of me. I nearly fell but managed to climb up and sat down to wait for my heart to start beating again.
