I am stumped as to why no one has mentioned “Hit the Penny”, which was a popular, if rather sedate, street game when I was growing up in Brooklyn. It used the sidewalk blocks, and between two blocks (on the line) you put down a penny, nickel or quarter—and then you stood at the edge of the two blocks and hit the penny. If it turned over, you got two points—first one to twenty one wins. The catch—when either player reached twenty, they had to back up one block, thereby making it harder to hit the target. What’s the deal—how come nobody even mentions this game. I play it with my son now in LA and we have a great time.
