Ok, the thread about renting your car reminded me of a question I had about enduros: do most of you car owners who participate in enduros treat your co-drivers as renters? As in, do you typically charge a fee - that takes into account event costs like entry fees, gas, tires, etc., plus a "rental" fee - for them to participate in the event? I have a pretty good idea how Kirk does it with Pablo, but I'm wondering if that's the norm?
