This thread probably doesn't belong in this forum. You probably should move it.
Do you mean Avon Old Farms and the Belmont Hill School? Both are excellent schools with excellent hockey programs. Major differences are (1)Belmont Hill is Boston preppy and AOF is Connecticut preppy (2)Belmont Hill is mainly a commuter school while AOF is mainly boarding (3) AOF is more structured -- they have required study time, etc.-- probably better for the student who needs structure.
