I love doing LL, its alot of fun. In general the atmosphere is much more intense than a Freshman HS game, perhaps because of the closeness of the field. Something is lost when you move to the big diamond for sure. The kids that are mediocre players just seem to stop caring from age 13 on, which is very sad.
And don't anybody go ragging on LL umpires who do just LL. Those guys umpire in front of thousands come tournament time. And its just as difficult as doing a state HS playoff game, if not more difficult because everything is so much faster.
Just a pet peeve of mine, I love the big diamond as well because its more real baseball strategy (no more running to 2nd on a walk with a man on 3rd).
