Ben,i would not normally comment on a subject like this,but to infer converted is a dickhead is a bit rough as i believe he's been involved in motor sport for years.
Based on my own knowledge in running events(cams)where insurance,safety areas,permits,paperwork,licenses etc.etc.the amount sounds about right but still on the high side.
Now reading between the lines none or very few of these normal requirments are to be required on this occasion.

As has been stated not even a fire extingusher is required...thats got to be asking for trouble and god help the person who's name appears on any documents should the worst happen to any poor sod on track,i only hope they have good lawyers.
As a bench mark i pay Queensland Raceway $80.00 for a 4 hour practice session on thier nominated days,this is run under AASA rules and regs and full safety gear is supplied(flags,ambo's etc)by the organisers and all cars must have all the right stuff on board also.

So let me just say,i don't think Willmington is doing you guys any favours if in fact he is pocketing the full $150.00 per car.
On the other hand,i don't have to run a V8 Falcon either.

End.
