We lived on 169th St. The old P.S. 168 had a pole that was cast in a roll away concrete heavy bottom. That was used to close the street to traffic and that street was considered a “play street” but only when school was in session. We used to roll that sign out AFTER SCHOOL to close the street for our variety of games, stick ball or roller derby. People were so considerate then—people driving cars never rolled the sign away so we had the whole street to ourselves. Fun, fun, fun.
