I've been to boyne and can say that it is big by Midwest standards. You probably won't find pow unless it dumps some snow, but they have several terrain parks, a snowboarder x course ( that doesnt sound like the right name). They have lots of groomed runs. I stayed with a group of guys at the village at disciples ridge. No trouble there, although I have heard bad reviews about the one place they have, I think its called Edlewies or something.
Plus they have an indoor water park!!
