What's with the fire extinguishers in every pic??
Them's the rules, no fire extinguisher you don't get on the field.
Yep, dems da rules... And it's actually a good idea to carry one in every car.
There's a little box that has to be checked on the judging sheet. and it does have to be charged.
BTW, the first time you run over one under your wheel, you realize it is better to put it beside the wheel or someplace noticeable in the car (like the trunk).
