My bedroom has a very solid door and a deadbolt, and is in the basement, and actually doubles as our compound’s safe room. That is (a) true, and (b) for my father, who has checked this blog 96 times in the last five days, according to my blog-counter. Hi mom & dad!
(Also, to my knowledge, the safe room has never been used, and is not expected to be needed anytime soon. That's why it's a bedroom, now.)
