Arden,
I would think that anyone that any of the main core of drivers brings along will behave in a proper fashion, however I understand and agree that we have to be careful to ensure that things don't go the wrong way. I'd love to see more of the past drivers return on a regular basis. IROC is definitely a big attraction for them since its just driving involved. Once someone has a good time racing the IROC cars, they will likely want to get/try their own cars in some of the other classes.
