I don't wear a helmet on my road bike.
I understand the pro-helmet argument, but also accept the dangers of not wearing one. Like many have said, it really is all personal choice. I for one don't wear one because I hate the feeling of it on my head. Also, and it is a pretty stupid reason, the girls here in Tallahassee seem to think it is hot when the biker guys wear skull caps, bike hats, or just hoods. : /
I enjoy reading this argument though.
