Car in the barn and you take the keys out? Why? Can someone open your locked door?
Where do you keep your car gun? In the house?
Not joking but, my keys are in the cars and the barn door is locked.
If in the event, there is a fire, who will be able to find you keys to move the cars out?
Way back in the late 60s, a club member, kept his 66, in the garage and his bed room was over it. His vette was chained to a loop of steel in the floor.
Yep, they got it while he was sleeping.
IF, they are going to "GET" your car, you or anyone else, will not prevent it unless you are armed and in it at the time.
Be warned, it aint worth your life.
