My organization has seen a one team per level growth spurt this year (Baseball numbers are down about one team/level) in a town of about 25,000. In my opinion the #'s tend to reflect how the older teams are doing and how much exposure they are getting. The young ones look up to the older girls and want to follow in their footsteps. We put a premium on the older girls working with and mentoring the young ones and it is paying off for us.
