Seems to me as if you could generate a list of all the racers that showed up to the event, that the group as a whole could file a civil suit against Pinks, even if there were some stipulations in the entry agreement. End result everyone could recoupe their funds and maybe a little refund for their time and traveling expenses.
Lots of hard earned money wasted at the expense of a Pinks, They should be held accountable, just like the guys who got banned for oiling down the track.
