Lived in Kentucky for 21 years and never came close to being the victim of a tornado, earthquake, or hurricane.
I agree with both of you:
They need to get the hell out for a week or two when these hurricanes hit, then come back.
I also think you're both wrong though. People can't just "move" whenever they feel like it, it's a huge financial decision that most people living there probably couldn't do even if they did want too.
But saying everywhere else is just as risky as living in New Orleans, a land mass that is quite a bit below sea level and a target for huge hurricanes, isn't true. There are other places that dangerous, but they're not as common as you're making it sound.
