At 10:30, right after my event, there will be a five-dance showcase by a professional Latin couple who was on "So You Think You Can Dance" (which doesn't mean much for me since I don't have a TV and haven't kept up with the show on Youtube, but is definitely exciting for others -- but great dancing does mean something to me, and it will be that!).
The daytime session is free for spectators, and the evening session is $10 (free for Stanford students, more for the best seats). The competition is in the Arrillaga Recreation Center at the corner of Galvez and Campus Drive on the Stanford campus. See the Cardinal Classic website or the Palo Alto Daily News article about it for more information.
Oh, and make sure to find me and say "hi" if you do come. :~)
