Rick, SOMETIMES instructors race for free. I instruct at DE events, do tech and registrations at Northeast races, and teach the comp school, but I pay for all my events outside the northeast unless I am instructing at that event. At Hyperfest in the MA region the schedule is almost impossible to instruct and race, so I just pay.
The instructors school here in the NE is usually a paid event for the prospective instructors as well. Not everyone ends up passing or wanting to instruct after they get a taste of it.
You would be a great instructor, don't let 200 bux stand in your way, hell thats less than the price of 2 toyos your gonna burn up trying to keep me behind you in September!!!!!
