I was thinking the same as you were Dave S. I remember growing up in NYC and all we would do was play Skully.
The funny thing about it is about two weeks ago, I was at my parents home and we actually brought up the conversation of playing skully as kids, as I try to explain to my wife (who is originally from California) the rules of the game.
My most favorite memory was: this one summer in Prospect Park, they had a Skully tournament, that yes, I did win. The prize, an official fold up Skully board. That I unfortunately and regretably lost.
I am going to have to make one and show my kids how its done.
