Hill School just happens to be the premier destination for field lacrosse and Canadian kids wanting to go to elite US schools. However, Culver Academy is also top notch and they are in the discussion because they have Canadian kids attending in droves. I agree with you...I am from Philly and with unbiased perspective believe that Long Island Lacrosse is consistently superior to Maryland. Don't agree with the Public School requirement to be considered a hotbed. To me a hotbed is simply an area that consistently yields top notch talent and nothing more.
