If I had a dollar for every person I have seen wearing a helmet that is so ill fitted it's mind boggling I would have a lot more dollars. I usually assume they bought their helmets on line and set them up themselves without any assistance from a LBS or friend knowledgeable about proper helmet fit. There was even a neurologist in my local club whose helmet left almost his entire, large forehead exposed. You would expect something different from someone is his profession.
