I think many people are being short sighted on this news. Will the Cup cars put on a good race on the dirt at Bristol? Probably not. It will still be a stock car with very limited changes made for the dirt. It is not like they are going to be moving to a Rocket chassis for the race. However, it is going to be a lot of time/effort/money to convert it to a dirt track. I would expect multiple series to run on the dirt. Definitely a WOO sprint car race. Definitely a WOO/Lucas Oil Late Model race. Those races would be much more interesting than the cup cars.
