Looks like close to a wash for cost of living. !8% higher cost of living but avg 15% higher pay for similar work. The Bay Area is one of the most culturally diverse area of the country. I have lived in around the Bay for most of my life. Traffic is terrible but you can make adjustments. If you are looking for a new life experience I say go for it! Then you can herf the the Bay Area Brothers of the Leaf(BABOTL)!
