C'est moi, at about 4 0r 5. The back story is this. We were at the beach with a small fire for cooking hotdogs, and I was gathering small pieces of wood for the fire, and adding them as needed. One piece had a waxy substance on it, and shortly after I threw it in, KABLOOM! My best guess is that fishermen at that time used dynamite to scare away seals , this one failed to blow and washed up on the beach. It was later estimated it was a half stick.
I have NO idea why I was smiling at this point.
