At book signings, and events where I am teaching children how to shoot marbles everyone (parents & children) wants to learn how to play marbles and want to know where they can play. My idea is to build some portable rings and set them up at community centers, museums and schools. I don’t have a clue about how to build such a reliable, stable, smooth board, that is easy to transport? I describe the game Ringer (ten-foot ring etc) in my book but how big are practice rings? Bruce Breslow has a marble table ring and Steve Sturtz described a smaller, but portable “Tap Box” being used by marble players practicing for the National Marble Tournament.
