Thanks for the links, suggested towns and other google-able information. Some of this reinforces other information we've gathered so far on towns, which is great.

I am wishing we had more than just our sense of his intellect and ability to go by. Maybe he's optimally gifted, meaning he'll probably be ok in a regular classroom? Particularly a classroom with some other OG/HG kids?

Is it really possible that we could have him evaluated by a professional familiar with gifted kids, and we might be told he can't be served well in a regular classroom with his age peers? Or are we borrowing trouble to worry too much about this, given that he's doing pretty well in current school situation?
How many questions can I get into this post!
