i broke two of my finger tips split them with a flex fan.i was at the drag strip. my friend walk me over to the meat wagon ask me if they hurt i told him only when the wind blew thru them. they gave me a ride to get them stitch back up . i was young then. i was in a big hurry to get the car to the track . left the top guard off the Gto and took the rad cap off with engine running. it sounded just like playing cards in a kids bike spokes
