Part of what makes autocross so inexpensive is the shared work load. Each person is assigned a work station. You will most likely be assigned a station on the course where you will reset hit cones, call them in and flag cars in case of an issue.
Each person works for one session and drives the other. We have 4 of these sessions and your participation in the working portion is vital to the operation of the event. If you do not show up to work your station then the event stops until we can find you or a replacement.
This is the golden rule of autocross, you must work your assignment, leaving early without cause will ensure that you are not welcomed back at our or anyone else's events.
