The Chi-Town Squares are offering free introductory square dancing lessons to teach you how to swing, promenade, and dosado to a wave--or at least find out exactly what that means. The intro lessons are offered tonight and next Tuesday, September 16, at 7:30 PM at the Ebenezer Lutheran Church (1650 W. Foster). (There's another class at the same venue on the 23rd, but that'll cost you $7.) No experience is necessary, and the Squares will set you up with a dance partner if you don't have one. The Chi-Town Squares are a gay and lesbian square dancing club, but straights are welcome, too. Call Michael at 773-561-5691 with questions.
