Photo by myself, in Park Slope, Brooklyn.
A fire occurred next door to our apartment building not long ago. Firemen took a ladder up to the roof and broke through a rear window to get inside. They also took a chain saw to parts of the roof.
Mark and I stood watched the whole thing from our apartment and were amazed that the firemen walked around on the roof without any fear of falling through. (I would have been a quivering mess).
Brooklyn is a densely settled area, and any fire has the chance to spread very easily. The owner was home at the time and escaped unharmed.
