Something that has caught my attention viewing other people's vids is how many of you guys runs with your visors up (Sam, Eddie, Casey, JP, DF etc).
I know that for myself, one too many times during a middle of an autocross run, a spec of dust would get in my eye making for a not fun next few seconds. I can see not putting it down if you wear glasses (or sunglasses), or putting it 90% closed to keep some air circulating. I even went ahead and got a darkend visor to encourage myself to run with it down. Just my random Wednesday thoughts.
