I really don't want to add fuel to this fire but after I picked up a co-worker off the ground I have to say I agree. He slid out on some sand about 1/4 mile from his house and was dazed, confused and stumbling around but still alive. His helmet was cracked in half as I'm sure his skull would have been without it. This is a guy who regularly commutes 10 miles to work and has ridden across the country several times as well. In other words, very experienced. While it probably won't happen to you, it just might.

And don't worry about feeling uncool with your helment. I leave mine on while grocery shopping since it's easier than taking it off. Flaunt your Fredness!
