If DEI makes it through the next contract with him AND Teresa really means to give DEI to Sr's children then all will be fine. If not......all bets are off. I am sure Jr fans will follow him anywhere and so will Budweiser and lots of other sponsors.
Charity exhibition would be a good idea but Budweiser won't let him drive anything but the 8 and the DEI Busch car. Howver, I am willing to bet that if they had a prominent spot for their logo on that Goodwrench car they would agree!
I'm not sure about his own JR Motorsports cars, he has expressed an interest in driving one of those. The Budweiser contract is why he can only be the flagman when many of the drivers go to Pevely and I-55 and race the dirt track cars.
