What a fun site brings back such wonderful memories of youth! I grew up in Brooklyn during the 70’s and during the summer all the kids on the block (and it seemed everywhere in NYC) would play Skelsies (or Skully), morning til night, we’d even play it under city street lamps. The most popular cap that we used was typically a milk jug cap and we would fill it with either melted crayon or putty clay as well. But, I haven’t seen any children play this game in years, seems as if the game has disappeared. But, what great memories of a fun game played on the streets of my youth.
