...do you own one for when you are required to wear one?
By required to wear one I mean for an event, such as an organized ride, race, etc.
This is not a troll post. I am just wondering what the ratio of those who own a helmet to those that do not. For now it has to do with those that do not wear them on a regular basis, but may at least own one.
Please explain your answer if you wish, especially if you do not own one but participate in events where one is required anyway.
