Welcome Kazzle! I sent you a PM (flashing envelope message). Can you tell us what your son is interested in and what his personality is like? There are many options in the Twin Cities, including a large GT homeschooling community if that is an option/interest. Each of the schools has its own personality too, some better for very self-motivated learners, etc.
With PG kids, sometimes what works for a while doesn't work in the next year, or the next 6 months. I'd be wary of moving, unless you plopped yourself in the midst of a bunch of options. With open enrollment in MN, you don't need to live in district, there just needs to be an opening in a particular school you're interested in. Plan on doing a bunch of tours, and ask for names of parents with PG kids who are willing to talk with you.
You will probably have more luck on the MCGT yahoo list available to members.
