BB27,
I agree with you, the field is too small. Why have 12 year olds playing on a T-Ball field? At 12 years of age, a good pitcher can over power most batters at 46 feet. Next year at 60 feet, they have no fast ball. I personally like the AAU, AABC etc concept of graduated fields, every other year move them to a slightly larger field. That way they don't have to go to a 50% larger field when they turn 13.
