When I was a kid all the small stores used to sell fireworks. I remember the different rockets, cherry bombs, silver bombs, whistling bombs and repeating bombs (a small one goes off first then the big one), colorful crackerballs, roman candles and Duck Brand firecrackers we called checker bombs. Also had the cheaper red devil firecrackers, the ones with the very fast fuses, These fast fuses gave us fast reflexes after enough blew in our hands. Don't remember having any mortar shells though. Those were the days and we didn't need no stinking permits.
