I'd be happy to prove you wrong. I live in Utah, and BYU hosts Nationals every year. In Utah Valley, almost every High School has a Ballroom team, and there are several studios all over Utah. In fact, as far as Youth and Junior teams go, Pleasant Grove and BYU have the top teams in the Nation, as does Center Stage, which is hosted from Utah Valley.
If you live outside the Valley, then it might be hard to find a team or studio, but I'm not sure. I just know I've been dancing for four years, since I was twelve, with several different studios and directors. We have many, many top instructors in the valley, coaches who have produced national and international champions, and everyone around here loves ballroom. If you want to find a studio near you, I'm sure you can find something, and I'd be happy to help if you post here again. Good Luck!
