What about when your helmet is dangling from the handlebar when the wind knocks the bike over? J/k, it was very visibly cracked on both sides; took it yesterday to the LBS I bought it from, and the owner kindly gave me a great deal on a new one. First time I ever actually destroyed a helmet, despite several (low speed minor) crashes, and my head wasn't even in it. I'm so lucky.
