here's a nice little write up on Wyoming
http://handgunlaw.us/states/wyoming.pdf<edit> If you have a Washington CPL you cannot legally conceal carry in Wyoming. </edit>
however you can Openly Carry. Places as listed in the “Places Off Limits” apply to those who open carry. Note that "No Gun" signs do carry the weight of law.
Anyone who can legally own a firearm can carry a loaded handgun
anywhere inside a vehicle as long as it is not concealed on your person and is visible. Wyoming law only
covers the concealed carry of a defensive firearm in a vehicle.
