A perspective to add to the conversation about living in Mariposa vs SF or elsewhere:
I am an "educated and independent" female who grew up in suburbia that, right about at the time I left for college, exploded into Silicon Valley.
I knew by age 18 I didn't want to live in suburbia. I then spent a few years living in a few big cities and decided that wasn't for me either.
I have spent most of the past 30 years living in towns with fewer residents than some urban apartment buildings. (In one case I lived in a town that had fewer residents than a fully loaded airliner

). Right now I live directly in a town of around 500 people and that is "too big" for me and I'm looking for opportunities to move outside of town (I don't want to change communities but I don't like having neighbors close by).
I should have added to my earlier post (about not having a hiking mindset), that it's not for lack of enjoying or reverence for nature, but rather that I have nature right outside my door and don't need to go somewhere to get out into it/to experience it, because I live "out in it" on a daily basis.
My point here is that we need to be careful about assuming or implying that everyone strives for, or SHOULD strive for, the same appreciation and participation in urban "cultural" life.
The range of personality types, introvert-extrovert spectrum, and work-from-home options are now allowing people to opt for rural/small-town life if they prefer it, while retaining whichever ties to "culture" they value.
MOO
