I was just alerted to a bizarre story on bikeforums.net. Mr Quadzilla says:
It's really windy here today in Silicon Valley. I was riding to work. Going 25 (according to Garmin). A gust lifted up my front end. Seriously, I got lift, and turned my front wheel a little. When my wheel touched the ground the fork snapped in half, broke...However it was really windy, windy enough to snap a cable on the Bay Bridge.
