I rememember three week ends rained out, about a 1/4 of the feilds showed up for eliminations and hardly any spectators
I have benn rained out at Pomona more than three times(maybe up to six, I quit counting after three) in thirty years of racing thier
The only good thing about Pomona being rained out was I lived less than 50 miles away so it was a one hour drive each way to attend the rain out days
