For the first time, local salsa instructors James and Milton Cobo will offer an intensive three-month course in the New York Mambo. Their “Mambo Semester” begins Jan. 22, and students from the beginner to intermediate level can still subscribe at their Web site (www.cobobrothers.com). Various rates are available for all or part of the 12-week sessions. Classes meet on Wednesday evenings at RTP’s Montas International Lounge (directions on their Web site: www.montaslounge.com). Register now, before the New Year’s motivation leaves you. –Sylvia Pfeiffenberger
