You bring back many memories with that one. Chinese firecrackers, Cherry bombs, bottle rockets etc etc. Too much fun. It was as you say, after that, we had to drive out to the desert or even Nevada to purchase. July 4 was never the same!
Of course they were illegal in our county so I swear I never ever did participate and I promised not to do it again. /s
SO true!
BTW, if during the early 1970s you saw a Freedom Fireworks stand in the NorCal corridor from Sacramento north to Yreka, chances are I was on the crew that constructed it. Dad had us going from dawn to dusk, but it paid well (for back then)!
