I'm a transplanted Canadian, now living in rural Indiana. Our small city here of 10,000'ish people is an incredibly refreshing change from the 3Million population and bizarre traffic of Toronto Canada. I'm Canadian, my now-wife is American. We talked with each other for months to decide upon whether I moved to America, or she to Canada. Other than marrying her, me moving to small-town Indiana was the smartest decision that I've ever made. I love it here. People are so friendly, the cost of homes and the cost of living in general, gasoline too, are night-to-day less expensive compared to Toronto. I do not mean to offend anyone, although I likely will, I would never move to any Liberal/Communist governed State or city. I say what I think and am very good with being that way.
Back in the early 90s when I began flying HPR from LPR, I'd drive 9 hours from Toronto to Three Oakes, MI to fly. That club is now Michiana Rocketry. I attended a launch there this past Saturday. I achieved my L2 there in 93, if my memory is correct. I'm a member and the people are so great.
I'm also a member of what was Michigan Team 1, now flying from about 3 hours from me in southern MI. Also good people, two that I'd met in the 90s from Three Oaks are remaining members and old friends.
So, there are 2 TRA Prefectures that I know of close to me in Indiana, living midway between Indy and Chicago, which was something put forth by the OP regarding thoughts of relocation.
