It's located in the country,  fairly rural, but close to popular vacation areas.

Granted, some people do it, but what I've found is a lot of these young retirees basically end up doing the same thing non-retirees do: they volunteer a lot of time (i.e. work for free), or start a business, or do something else to fill in the time-gap.I get it: FIRE is a popular concept right now, but aside from it being the latest buzz-phrase....what does it have to offer you that a rewarding, fulfilling career and/or starting your own biz wouldn't offer?
