It's all speculation at the moment, from that article he could be angling for a full time drive or a one off race when the NASCAR boys turn up in Canada...
(Heck, if the Three Amigo's are smart they could arrange a back to back kind of deal so Tracy can run both races, no matter what series is his "home"
)
As for Champcar....it'll be a crying shame to lose Mr excitement of open wheel, but who knows, seeing what's happening on the other side of the world at the moment, there may be another famous Canadian to step into his Forsythe shoes next year.......stranger things have happened!
