And some quality of life issues, also personal, simply can't be easily quantified. I would personally love to live somewhere where real estate costs less, but hey, the bay area keeps pulling me back. The weather is gentle, you have access to the entire world right here, the job market is way above average, so there's lots of opportunity.
Good luck to you.
I don't know the exact numbers but just to guess I'd say that for every one of you Oregonians moving in to Cali there's probably at least 10 moving out. Many of them to the PNW just to get rid of Big Brother gagging the hell out of them. You're a brave soul but welcome just the same and good luck.
Love CA, don't get me wrong...but I know no one who ever moved here to save money on taxes!!! Best to you!
