Your neighbor to the east, Nevada.
No income tax. What we'd normally pay in income tax is instead paid by the idiot tourists who come here for the privelage of throwing their money down the toilet.
Lower ticket fines. We have tickets, its true, but the NHP generally lets the minor offenders go so they can catch, say, the drunk truckers doing 70 through a school zone, in a snowstorm, with no chains. Even if you get a ticket the fine is usually pretty low, at least compared to Cali. Just watch out for the local PD; half of them are the guys who the NHP deliberately kept out because they didn't want their abuse-of-power attitudes in the organization.
Low sales tax. You're used to, what, 14%? The highest we have here is 8%, and that's in Vegas. The northern part of the state ranges from 6% to 7%.
