Hola Everyone, This message is actually for Mike Osborne . I see that you and your wife are professional ball room dancers who are transitioning to mambo thru Mambolab . I met and befriended a professional ball room dance couple over 20 + years ago at the Puerto Rico World Salsa Congress held at the Caribe Hilton Hotel in San Juan. . They are Tony and Melanie ball room dance champions who also loved salsa ( I hope I got their names right , long time ) We met again at several more congresses in New York and Puerto Rico. They eventually retired from competition and opened their own dance studio iin New York , right in Times Square , teaching salsa & ball room . They are an inspiration to others making the transition to salsa / mambo ! Take care and keep on dancing !
