Depends what I'm doing. I'll wear an open face helmet for field drills but if there are rocks or trees around I'm wearing my full face dirt helmet. If it's a combo day I err on the side of safety.
I'm not vain but nobody's face is improved by crashing on it.
I'm makin' ninety miles an hour on my German motorcycle
I hurt a little less every mile west that I go.
