The number of kids in club sports have been climbing...if you like the scholar athlete model, club sports is where it is at.
I know that while FSU offers less than 20 varsity sports...they field competitive (they also have recreational) club teams in men's and women's Lacrosse, men's soccer, men and women's rugby, crew, equestrian, cycling, fencing, field hockey, ice hockey, wrestling, water polo, triathlon, racquetball, skeet and trap, roller hockey, table tennis, bowling, sailing, men's volleyball,....and let's not forget Ultimate Frisbee and Quidditch and Paintball....among others.
