Not sure where to put this but it would be interesting to see a listing of what the girl's clubs' affiliations are (where directers and coaches are from or significant amounts of players). I'll start (and feel free to correct me if you think or know that I'm wrong):
Liberty: Manhasset, North Shore
Express: Ward Melville, Kings Park
YJ: Northport, Farmingdale, Cold Spring Harbor, ESM, Mt. Sinai, Lindenhurst, Garden City, I'm sure I'm missing some
Top Guns: North Babylon, Northwestern
fl$: Stoneybrook, CWPost
Premier Lacrosse: Commack, HHH
I know top guns draws players from one end of the island to the other, north and south shore.
