Dirt track at a drag strip??

Las Vegas Motor Speedway has the asphalt oval, dirt track, and drag strip all next to each other and they don't seem to have an issue with it.

We went out there for the Nascar race one year and the World of Outlaws was also running. Went to the Outlaws Wednesday and Thursday night, hit the casinos on Friday and went to the Busch race Saturday, and cup race on Sunday. What a trip!!!
