Matt - I don't look at this list often and missed your post, but we kiteski in Maine on Sebago and Long Lake which are close to Portland all winter. I think last weekend might have been the end unless we get some freak cold snap. Check in on http://www.kitesurfingboston.com
and check the forum or go to yahoo groups and check out NEKS (northeast kitesurfers) A lot of the New England guys keep in touch through those two sites. We'll catch you next year on the snow.
