I keep you in mind when I think about moving back to a rural location, and admire the way that you've woven your family life where you are.
Would you ever consider relocating for an apparent 'passion' (a la the other thread), when it's moved well beyond an interest?
I've often wondered if, in retrospect, we should have moved about 6 years ago, when eldest's passion for music took off. We spent a few years doing ridiculous (and yet still insufficient) amounts of travel to get her some appropriate training at her level. But ... our house has been fully paid off for a decade in a depressed market, and dh has spent almost 20 years building a multi-faceted small town medical practice that (a) cannot be sold like a big-city practice would be and (b) could not replace him easily, which would likely leave the community and many of the people we love in the lurch. It would be a huge financial and social-emotional transition if we wanted to extricate ourselves. And he really dislikes the flavour of urban family practice, where you are more of a referral-broker and the moment a problem gets the slightest bit interesting someone else takes it over. So it would have been a lousy move for him and for the community we love.
If we had a do-over, we might try to find an almost-equally-rural community that was logistically closer to urban amenities. That has a nearby airport, or is within an hour of a small-to-medium-sized city and has a bus route. I still think that small town rural life has been the best choice for us. On Friday night we attended the community choir concert (ds and I accompanied) and feast where we knew everyone and the warmth and caring were just overflowing. Last night we had a power failure, and one of my kids' teenaged friends walked in the dark up the highway to our place, and my three and he spent 6 hours in the yard building this (below) by the light of headlamps (inspired by a long-time friend of ours here who is an internationally-renowned snow and sand sculptor), and then there was a tea and hot chocolate at 2 a.m. heated over the wood stove. There's so much that's wonderful here, so much that has helped shape my kids into the wonderful people they are, and grounded them. Would we trade it for some dance classes? I don't know.
