That's something you don't see every day...

...or at least I haven't seen it before, that is. I'm just back from an exercise walking session, and while out I saw something like one of these being worn by the driver of a motorcycle that went past.

Yes, a motorcycle helmet that has a mohawk. That was rather startling, I must say.
