Oh man, they have them all over the country for regionals, I definitely recommend you hit one up. I have a few friends going to Vegas later this year for nationals - REALLY looking forward to it!
Yeah, I don't get the board shorts thing. A lot of "purists" want to do away with bikini, but I think those gals have a really hard job ahead of them as they have to develop muscle tone without dropping body fat too low, or appearing masculine. What's so pure about covering up the largest muscle groups in the body.
I too think of the competitors from the 80's and 90's when it comes to physique. Well balanced, good muscle bellies, and amazing symmetry. Zane, Wheeler, even Schwarzenegger (balance was one of his key trademarks) definitely come to mind.
