Thank you Pete.
Going to hide under the mattress in the sub-basement.
Since in KC the city the sub-basement is where they keep the electrical transformers and stuff, make certain those shoes have a lineman rating unless you think all the waterlines break and your vault will fill up in which case it probably will not matter!
("Not kidding! Not a Joke!" Try a search on Youtube; "Electrical lineman boots" ! )
I am not far from the KS/MO border and I do not worry too much about earthquakes, even from the New Madrid. (I still have earthquake insurance for about $10 a year!)
