It ain't just Californians. Here in northern New England it's people from Mass. or Conn. They wanna move to the country to get away from all the city crap, and (in theory) enjoy the "simpler life" in the country. Then they want all the amenities, zoning, etc. they had in the city.
I'm sure it's true in every part of rural America...only the cities/states the crowds come from change.
I grew up in Mass.. work in one city or another virtually every day. Typical day is 200 miles or more in one truck or a van.. in traffic traffic traffic. ..I hate people...well..most people these days. As far as me moving somewhere and wanting to make my new home like my old home...no. ..My eutopia is a 10-15 acre lot, neighbors with similar acreage. A 2500 sf home and a 1500 sf shop, property cost 500k ish with a tax bill sub 5k a year. Within a 15-20 minute drive to basic shopping and restaurants. Minimal public services outside of L.E and F.D. And within a hour drive to quality healthcare. No snow, No earthquakes, not in tornado alley. I know you can't predict Mother Nature, but some places are more prone to weather disasters than others. I grew up looking at the Atlantic Ocean every day.. I'm over it.... I don't care to see the ocean at all. Trees, mountains, rivers, lakes.. more my style.
