Washington is an Open Carry state. In this one respect it is superior to Texas.

Wow! That is amazing!!!!! Good to hear.
In these states, open carry of a handgun is generally lawful, but the state may lack preemption or there may be other significant restrictions. The limitations and/or lack of pre-emption may mean that certain areas of these states are, in their judicial system and law enforcement societies, not very friendly towards the practice, although this is not true in all of these states.
The part about "not friendly" sounds about right. I personally have never seen a civilian open carry here in an urban area.
