Ruh-roh... do you know what a "dog pile" is? You may soon find out because THIS topic is only slightly less contentious than chain maintenance!

Yeah, I sometimes ride sans helmet and, like you, my helmet has a mirror... During the summer though, I value sun protection so I wear a brimmed hat, bigger than a fedora but smaller than a cowboy hat. Also, walking around in my hat is only SLIGHTLY less goofy looking than carrying my helmet like a purse...
