Drills

So the past few wednesdays i have been blessed to 'tutor' 1st graders with reading. Its so easy and it goes by so quick. My husband teaches middle school and has stories galore about the craziness of them and their families. Somethings could be prevented and most is just cause people need Jesus and need to seek after him.
Yesterday as we were tutoring they had an 'extreme weather drill'. where everyone calmly goes out in the hall, turn toward the wall sit on their knees and bend over like a ball with their hands on the back of their heads. one teacher said its easier to keep learning with a broken hand than head so keep your hands over the back of your head.
The only drills i remember are the fire drills, where you go outside and stand in a line and pretend to watch your school burn down. I have never lived anywhere that they drill for earthquakes or extreme weather...have you? What drills did you do as a yungen?
