Despite not currently residing in Colorado, I'm a Colorado citizen. I pay Colorado income taxes. I vote in Colorado elections. And I'm seriously considering Wyoming as an alternative to Colorado. Wyoming has no state income tax and is very supportive of firearms rights.
Colorado on the other hand, has an income tax of 4.63%, is constantly attempting to either find ways around TABOR, or otherwise render it ineffective, (the usual method is to call them "fees" rather than "taxes") and is currently attacking firearms rights without regard to Colorado jobs or rights (read section 13 of the Colorado Bill of Rights on page 5).
