In North Carolina a new law went into effect this year... you have to wear a DOT approved helmet or get a ticket if caught and that tickets comes with points against your licenses! I used to wear a brain bucket in the summer time and have gone to a very nice good fitting 1/2 helmet for the summer months, one that does not make my head look like a mushroom. Took a long time to find one that fits and looks good. In the winter I have a 3/4 Bell helmet with a full face shield that keeps the cold air off my face at interstate speeds. According to the reports I found say more than 1/2 of ALL motorcycle fatalities riders were not wearing a helmet. After witnessing my son flip his brand new BMW end over end after a dog ran out in front of him at 70 mph right in front of me, I no longer have a problem wearing a helmet. Our group of 10 riders were out on a cool winter morning and I was the bike behind my son and saw it unfold right in front of my eyes, he could not have avoided it. His full face helmet was scraped up from chin to the top of his head. If he was not wearing a helmet he would be dead or his whole face would have been scrapped off..
And yet we (you and I both) still wear the 1/2 or 3/4 versions instead of the full face. This thread proves style and comfort trump safety in the vast majority of cases, even after witnessing the results.
