Having been invoved in Supermoto racing the last two years I have learned that when there is NOT a permenant, quantifable track with proven historic information the insurance policies are often negoiated on a per event basis. everything that is negoiated becomes a 'three ring binder of the covenant' sort of thing.
Usually there is an independent third party walking around the pits with a big three ring binder under his/her arm (more recently an ipod thingy) observing.....just observing
In fact, they became a good tip off that something was lacking.....if they lingered in the isle a bit too long....look around the pit and grab the fire extinguisher out of the trailer, before a race official could follow up and correct the problem.
in the event of a 'issue' that three ring binder became THE decision matrix period....the race rules were only the beginning of it...public health, traffic control, hours of operation, security were all covered.
any doubt who is driving this bus?

by the way if you really want to feed your own personal insurance rant.....ask a Candian racer what the difference is between the release statments north and south of that border....guess which one is three lines long (including the line for your signature) and which is three pages long??
