ok ffff that sucks, oh yeah I'm in socal and near SD a few times a month for work. Very nice weather, freeways suck, cost of living is too high that's why I plan to stay away from CA NYC etc.
My next choice is somewhere in North Carolina? It's got a decent tech mecca and I'm sure some areas are sparse with good greenery. Cost of living seems to be lower than CA. I'm not adverse to outside of the country for a nice uncrowded, relaxed place, that doesn't have tons of traffic or skyscrappers.
North Carolina is great (my homeland), but I don't think you will like the temperature ranges there, either.
It gets goddamn humid and hot as balls (Seriously: your balls will be sweaty and gross) throughout the summer. "Winter" doesn't always snow--well it depends on where in NC, but since you say tech area, that only means Raleigh and Durham area--but it is usually icy. It also can get really freaking cold weeks at a time. Fortunately, winter doesn't last all that long.
The coastal area is certainly milder, but then you have to deal with tropical storms Hurricanes each year. It's also rather sleepy along the coast. It's great if you're really into the ocean, because there isn't much to do out there,
year-round, but walk up and down the piers, ride a boat, and go to Pac a Sac for your expired groceries.
For RTP area, great cost of living, and a place to retire, I recommend Hillsborough....before it gets too popular for that exact reason. Well, may be too late.
