Ruby, those drills are important.
You can't visit Manhattan if those types of drills scare you. They are conducted all the time there. I even heard Steve Wynn talk about how they deal with the threat of terrorism in a place like Las Vegas. Think what a target that is. It is a little disconcerting when you get caught in the middle of one of those drills. A drill was conducted at a Manhattan hotel I was staying in a few years ago. But, I think we should take comfort in them. But, thank you for the heads up.
