All of the things that you think it is, it isn't. Don't fall for their your kid is the next BU or the like player tag line. If your kid is the next "that" player you've already been contacted by the coach, staff or somebody closely aligned with the school or organisation. You can do all of the same things they do. All they do is send letters out to junior teams and schools hoping somebody will be interested. Normally those who are interested are jr teams who invite you to open tryouts which are better known as money collection tryouts which offer no real chance for an opportunity to play. There was an informative discussion about the jr teams tactics a few weeks ago here. Good luck!
