One of the problems with ERE is to find like-minded people locally. This is an issue both pre-FI in terms of having sympathetic people to talk about ERE to and post-FI in terms of having people to do things with when everybody else spends most of their time working, watching TV, and attending paid events.
One solution would be to designate an "official ERE city" to which those who are interested would move. Obviously, there could be more than one such city, but I believe it would be helpful to agree on some cities, which could be officially supported so to speak. We may even have one in each state(?).
I'd model this idea on http://freestateproject.org in which states where judged for the alignment with libertarian values. Ultimately, one and a half were chosen: New Hampshire with Wyoming as a runner up.
In the same vein, maybe we should try to find out which states/areas are most suitable for ERE people.
So use this thread to post your needs and wants (big city, small city, access to hiking, train systems, international airports, bicycle friendly, low cost of living, low taxes on investment income, ability to work pre-FI, ... ) AND suggestions for such places.
Maybe then we can agree on something.
