What are the emergency drill rules for where you are or where you grew up? Drills were always the most exciting breaks in the middle of the school day growing up. Do you have any interesting stories about drills?

I grew up on the west coast, and earthquake drills were always to duck and cover under your desk. But when I moved to the Midwest I had no idea why we were all going down to the school's rec room for a tornado emergency, and not just ducking and running for cover. I don't think I learned about the using the bathtub as a safe place until a few years later.
