I wonder how many would have showed if they had not cancelled. I wonder if Byron, Cordova, Great Lakes, Havana and 41cancelled. NHRA ran yesterday till it rained before semis. It was what 52F? Set all kinds of records.
In the early 70s we started at Oswego in March in 35 40 degree weather. Sometimes snow piles would be along track. No spraying VHT etc.
Of course the average cars were not as quick today's bracket cars. But some RTE's were in 10s and 9s.
Cordova still hosts a Hangover Race on New Years if dry. US 30 used to do that.
