Does anyone run with the San Francisco SCCA? They have an autocross scheduled for this Sunday in Oakland and I have some questions.
First, is there a limited number of weekend memberships for events? Could I show up and not be able to run because I am not a SCCA member? I don't care about the extra $15 for the temporary pass.
Second, it appears as though the day is broken up into two groups - basically modified in the morning, stock in the afternoon. Do I understand correctly if I am running HS I don't have to show up until 11:30AM? I have not been to an autocross that runs this way before.
