I know some of the line dances, but I compete in couples dancing. Specifically, I dance ProAm with my coach, and right now I do 7 of the 8 couples dances: triple two step, nightclub two step, cha cha, waltz, two step, east coast swing, and west coast swing. Polka is the last one I have to learn, but we're putting that off for another 6 months or a year - I just graduated up a level and this year is going to be plenty difficult as it is, taking 7 dances to a higher level without having to learn one more.
