Dude. You can argue all you want about the validity of helmet laws, but don’t tell me that helmets don’t reduce horrible injuries. I have a 3 inch scar on my head where they had to put 6 staples in me to keep my scalp closed after I went off my bike the one day I couldn’t find my helmet. I think the padding’s kinda silly, but your brain can get seriously messed up from unlucky knocks that would only bruise elsewhere. Why take the chance?
(and most of those anti-helmet sites are just B.S. The usual argument is "well, they don’t provide much help when you get clocked with a car going 30 mph. Well duh; that doesn’t mean they don’t help when you slide into a ditch going around the corner.)
