Atlanta area. Average Ruby web dev salary for region and experience level. You can buy a McMansion (if that's your thing) for less than the price of a closet in the worst parts of the Bay Area. Poke around on zillow.com.
I don't live in the Bay Area, but I live in L.A.. Cost of living wise it feels like I do. I can't believe how much money goes to rent, and paying for lots of gas for commuting. The urban sprawl with lack of a good efficient means of public transportation, is pretty disgusting.
