It is interesting to read of the potential for Graham Rahal and Dale Earnhart to switch race cars in order to promote the National Guard. The information posted on several sites seems to indicate that Dale is worried that Chevrolet may not want him to drive a Honda (Rahal's engine brand) What do you think is the reason?

1) NASCAR doesn't want their driver in an Indy Car?

2) Chevy really has an issue with the Honda?

3) Earnhart is afraid that he may not have the skills to drive the more sophisticated Indy car? Or that he may like it?

Seems a shame that this could not take place in order to promote the National Guard.

What are your thoughts??
