Hello all. Just joined. I've been prepping for a couple years now. But there are a lot of knowns and unknowns. "There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns -- the ones we don't know we don't know." -D.R. Guess I'm here to see if I can find any bite you in the ass unknown unknowns.
