On the west coast it means lots and lots of Democrats! If you're "blue" we welcome you to move out to Cali with us. If you're "red" move to Florida... You'll fit right in!
Usually it just means you pay more for everything. From gas to taxes to housing costs. A half million dollar home in a southern california coastal town is truely a shack. Maybe 1000sqft tops. Or a "middle of the road" condo.
