After the success of Wednesday night's Mudsummer Classic at Eldora with the Camping World Truck Series, can one or both of NASCAR's top tours be far from getting "dirty,'' too?
"It might be sooner than you think," one source said.
Dale Earnhardt Jr., who fields teams in the Nationwide Series, believes running that running cars on the dirt at Eldora "would be fun."
"I think it would be good for them and for the series as well," Earnhardt said on Friday. "The trucks are such a neat choice because of the side force that they create with the way the bodies are on the trucks. I'm not sure how the Nationwide cars or even the Cup cars would run there, but I think it would fun for the series to have a couple of dirt races, to be honest.
"Eldora is the perfect place to have this all tested out, and obviously it seems to be really awesome for the fans and something they really enjoyed. So I expect that's something we could see more of. We'll just have to see what NASCAR wants to do."
