Depends on your expectation. It's a recruitment event where all eyes will be on the older relevant kids. No one will watch an 11 year old because they don't care. With NCAA likely to restrict recruitment till Fall of junior year next month, I'm not even sure how many people will waste their time going to the event at all. However, if you have expendable income and some free time, your kid will probably play some quality lax with some really good players.
