It's growing like crazy in the Chicagoland area too. Both of my boys play it and I've picked it up too. It's a fun sport to play. My daughter is taking it up too, but, she'd rather play the boys' game (full contact). It's still a club sport for the most part around here but that's okay because if you pay, you play, no cuts. They're also planning on introducing the sport in the middle schools in the town I live in.
The only time I've seen it on TV is during the NCAA championships. CSTV (College Sports TV) reruns games from time to time.
