Hi all, I have a friend who is a gun enthusiast and has many guns but no concealed carry license. He's more of a collector who likes to have fun at the range. He is going on a trip to Eastern Washington from Portland and wants to know if he can bring a few rifles and a handgun or two with him to shoot at the range with his family in Washington. From my knowledge, I assume it would be legal as long as none of the guns are loaded and are in his trunk (out of reach). Any input and/or help is gladly appreciated, thanks!
