i think that's a really good point Jason made above that people don't really know until they are there. Yes the coaches at HF are very accessible, but they end up talking to one guy (who may or may not be good) and are often distracted. Even parents (who should not but some cannot help themselves) talk to coaches and that means less availability. Ivy coach spent 45 min with a dad last year -- pretty amazing despite a line of boys waiting to talk.
With 4 fields at HF, it is sometimes hard for your son to find the coaches your son wants to talk to when they are assigned to one field and your son is on another, etc.
