looking for suggestions on leaving handgun in vehicle for open carry, when I need to leave vehicle to enter a gun-prohibited building. I don't like the idea of leaving gun plainly visible in car while away from car. open carry laws require gun to be in plain sight in car but I worry it may be stolen or cause alarm to someone walking by my vehicle. Don't think it'd be 'lawful' to put gun under the seat while I'm away from car. any suggestions?
