open carry is legal in WV...including in a car. (with the exception of two towns that had open carry bans that were grandfathered before WV adopted state pre-emption. i forget offhand which two towns.)
so, you don't have to lock the gun in the trunk when driving through west virginia. you can just take it out of your pants/off your belt and set it in plain view (on the seat, for example).
