I'm in the "target" wealthy group that these jackasses would like to soak for more taxes. When they attacked my wallet, I responded with my feet. I suspect many more people have figured out that they can afford to leave the socialist paradise of CA for more reasonable places. Red Davis and his minions are picking some gasoline and sales taxes from me as a consequence of business trips to CA. CA isn't getting a dime of income tax from me ever again.
Consider yourself lucky. I got hit with registering my car in CA after being there just three weeks on business. $400. Told them I was going back to AZ in a week and I was informed if I did not get CA plates, they would put a warrant out for my arrest and, if they could find it, seize and sell my truck. What made it even worse is they did seize my AZ plates and I had to get new ones (CA DMV wrote and told me that was a mistake but nothing could now be done about it). I've inquired what it would take to do a street fair or other show in California with out of state plates. They told me I could buy a limited permit (a week or so) for $45 to use their highways.
This was in 1992. Perhaps the laws have changed. For the worse I would imagine.
