Interesting, I was curious to see if the other states are catching up to NY (LI) in lacrosse so I did some research on Cherry Creek.

Cherry Creek HS has a student population of over 3,500 compared to 1,100 for Wantagh. So cleary their division would be different.

Also, found out that Cherry Creek was 2010 Colorado state Champs so I guess NY (LI) still may have an edge.

Seems like the have a pretty good program for Colorado:

"Besides 11 State Championships, 23 All-Americas, and many All-State awards, the Cherry Creek program has
had several Doc Stabler award winners (top Scholar-Lacrosse Player in Colorado), and has sent a steady
stream of players to top Division I, II, III, and Club programs across the country."
