It really depends on the league. Some leagues have several teams go every year, so those parents are more prepared - especially the older ones. However, after any team gets through their district playoff, they should be looking ahead. It looks like almost half the 32 teams at SoCal State qualified for Westerns.The unfortunate thing about ASA Nationals/Westerns is that it's a week-long commitment and many families coming out of the rec programs aren't prepared for that, especially when it comes to scheduling time off work and budgeting for an extra vacation.
To clarify, that's total for 10U and 12U combined.Good luck to your team. With over 80 teams, it should be a good tournament...
