So the bottom line is they wrote it in the rules that they CAN make up rules as they go along.

This is not found in the rules for Ventura raceway. I bet if I forwarded this to Cliff, he would have it added into the rule for Ventura for next season.
It looks to me like some high paid lawyers and contract writers wrote this section of there rule book also. Maybe we will have to show up with our lawyers in the pits with us to make sure the officials play by the rules.....
