It’s Miller Lite Carb Day at the track. For an hour this morning all the cars in the race Sunday got to put in some laps.

Here’s the Ethanol Car heading out of the pits. This is a view of it from the 4th floor of the media “pagoda” building.

Ear plugs are a must because it gets loud. I think one of the biggest thrills is the sound these engines make. Just to rev you up I recorded a minute of the Carb day practice session.
