Have you tried the MCGT yahoo group yet? I think you might find a bigger group of Minnesotans there. You have to be a member to join, but it's worth the $35 or thereabouts for the Outlook newsletter (including the summer programs issues) and other support.
http://www.mcgt.net/email_group.htmlWe're out of the Twin Cities area a bit, and our DS is just 5, but otherwise I like the looks of the Lighthouse program for our HG+ kid (from what I've heard anyway about it's one-room school feel where kids go at their own pace). I don't know anything about the Woodbury program. What sort of personality does your DS have? Does it seem to fit better with the styles of teaching (e.g., I think Lighthouse is more project-based).
Good luck! And that's great news that you have this choice.
