I remember spending many a summer playing in Brooklyn near the “safety zone” between Amersfort Place and E. 27th (?) Street near Brooklyn College. The “big boys” painted at least one, and possibly more, boards in the street on that bend – now, if anyone knows that neighborhood you can imagine how many times we had to get up to let cars pass in their search for the elusive thing known as a “parking spot” near the college. One thing no one else has mentioned is the sodder cap. We evlolved from empty caps to wax ones (I can still hear my mom yelling at me for using her good candles) to wax and penny ones and finally – the ultimate – sodder! What a blast you could get from that!
