All, I do appreciate all of the responses. Thank you Mana, as it appears you covered A the real experience. Thank you Aquinas for the interesting link.
I do not expect that too many people have experience with micro schools due to the micro aspect to them coupled with my assumption that there are not too many of these schools.
As for catering to gifted: if MG is included then large metropolitan areas could have relatively large schools that cater to gifted, but if only higher LOG are allowed then the micro aspect becomes more of a necessity. It was my hope in this forum I would have a reasonable chance of finding a fair number of folks who went the micro school route, or have children that are going the micro school route.
