there's a lake in topeka with a course on it that i've heard of a buddy skiing on in the past, but i'd suggest talking to the people at MoKan in Lawrence. Current president of the site is Todd Bays and when I was talking to them last week it sounded like they still have memberships available. The lake in Emporia is Super Lake, owned by Jason Lewis' family [an old Kansas University waterskiier]. They let my old team [kansas state] ski down there a good while back. They aren't BOSers, but if you need anybody's contacts let me know!
