Washington State. Based on a lot of the PNW members of another forum I’m on, guns don’t seem to be too hard to come by. I don’t think all counties do emissions inspections either. If red state really matters to you, just avoid king county (which pays the bulk of the state’s taxes anyways).
From what I can tell the education system there isn’t nearly as ass-backwards as many states in the south, so your kids won’t grow up to be dumbasses.
Also pot’s legal there now.
