 Yes, well, I've lived in this area for a long time now, and I well recall in Las Vegas we would give out warnings to get away from precarious positions, get off tall buildings, all the rest of it, when we'd light one, torch one off here. Well, up around the Bay Area, I could tell, I'd hear when the blasts were supposed to go off, and so I'd have my pendulum there, and it would actually move. The house would move past the pendulum about a quarter of an inch. Hmm.
