I love fireworks, I have been a professional pyrotechnician. The amateurs who live in the street behind me who set off aerial shells, in a residential neighborhood, where almost everyone has cedar shake roofs make me more than crazy. I'm scared to death they will light the houses on fire. They are setting off serious shells. By my eye, anywhere from 3 - 6 inch. WAAAAAY too big for the location they are launching from. They were doing it last night & they'll do it for the 4th of July....and probably some nights in between. If I could find out where they were launching from I'd have the cops on them so fast!
