Well, yes, that's most certainly true, but I've been outside in approximately 90-100mph winds and I'm still here.
Stay out there long and you won't be. I have a bike as well and I been well over 100 mph on it. If a person is protected and in a debris free area then it's not a big deal.
Housing 50,000 to 100,000 people in hurricane conditions wouldn't involve a debris free situation.
