In response to a request for the ‘weirdest’ skelly cap, I’d like to add that in Brooklyn, NY during the early ’70s we used the rounded metal feet from the bottom of Catholic school desks. Once we found how well they slid across the street pavement, many of the desks at school (St. Simon and Jude) were imbalanced. It quickly got out of hand and became an unfair advantage for those who were using the standard bottle cap with melted crayons (as the feet were much heavier). I’ll also note that most boards were made in the street with chalk (don’t remember any standard dimensions), but one year we carved a more permanent one into the tar with pocket knives. Thanks for the memories. Makes me think back on other street games like Johnny on the Pony, Ring-o-Leavy-o, Coco-Leavy-o, Slap ball, Box ball, the other game played on a box ball setup (2 adjacent sidewalk boxes) where you had to flip and/or move the popsickle stick or coin -sorry I can’t remember the name…
