I ran midgets from 1982 till 1996, never had a drivers side guard, used foam, or cardboard under my uniform around my bicep. The only time it really got my attention was at Belleville behind the V-6 of Higman, with Ken Schrader driving, that thing really kicked up some shotgun dirt clods. Made multiple bruises on my arm, even through the cardboard. One car I drove had an old style Edmunds type hood, but the cowl was not cut down, and the rounded corners of the top of the cowl kept most dirt out of the cockpit. I know we were going faster than 90 mph at Belleville.
