Was in New York City today and took the #7 subway from the bus terminal at 41st street. Well, there's an underground hall between the terminal and the subway station, and near the ceiling I see a group of some sort of raceway gutter (4 of them) that usually has covers, but some were missing the covers. Within reach of taller people. Not kids though. Most of the wires I could see were around #12. Probably not a serious hazard as most adults know not to mess with such wiring. Lighting circuits, not the 3rd rail power. You get this sort of thing when there's not enough budget to maintain things....
