"I looked at the map and photo of your Sacramento State Fairground page. I can add a few things as follows:  Circa 1959 there was a 1/8th mile drag strip at this venue. The staging lanes were just east of the road race course Turn 9 shown on your map. The strip was then the front straightaway of the road course, through the start/finish line and slightly beyond.  The shut-off and return lane was through loose gravel."
