This is a very new obsession for me, I've been a cottage skiier my whole life, but I only got into the course in late August of this year. I've always loved to ski, but not the way I do now. I live 10 minutes from the McClintocks ski school, and I decided to take some lessons on a whim, big mistake, now I am obsessed. I bought a boat to practice behind at the cottage, (old Supra) and I'm pining to get back on the water in the spring. So to be fair I've never been on Maui with a proper obsession.
@Jipster, the name is very familiar (that may be because I've been in his gallery or because it's also the name of the author of a book on Samurai history I have), but I don't know him, . I'm familiar with most of the names who are regulars on the North Shore, although I don't know any of them personally, I don't think he is any longer among them.
Back to the skiing bit, Maui is a magical place for me, but the ocean for me is all about surf, calm days are pretty much unheard of, (waves in the winter, wind in the summer) and there's no inland water, (well none that you would be allowed to put a boat in anyway) so a slalom course would be out of place there IMHO. There might be someone out there who would be willing to take you tow in surfing on a small day, dunno, but it has occurred to me, and would be for a skiier the quickest way to get into surfing.
