Same here. It was 1974 at the Keystone track, New Alexandria Pa.
Hand written,no reaction times Just 1/4 mile time and MPH.
To you that started drag racing on motorcycles,mine was a 72 CB350 Honda.
You bikers missed the dreaded bucket and rag at Keystone. When you drove to the tower to get your time slip as you were handed it if you lost someone was on the other side of your car rapidly taking a dirty wet rag to your shoe polish on your passenger side window. One swipe and just move along. Your night is over.
