I can remember only one neighbor, next door, that I'd describe as nuts. That Bronx neighborhood was crazy for fireworks, especially on July 4, but as a hobby maker of them I might've had a better idea of safety than some of the people around me. The next door neighbor was loading a 3" gun (looked like it was PVC pipe, not a good idea to use, in a bucket of sand) with a shell with bare match leader, and he was smoking a cigaret. 2 days later he was smoking a cigaret while filling his lawn mower with gasoline.
