Chuck is in Nashville this week and plans to visit with a guy he interviewed at the Indy 500. Brad Mayo is a “tuner” – he fine tunes street cars to make them run faster on ethanol blended fuel.
You can listen to Chuck’s interview with Brad about the finer aspects of fine tuning here: Brad Mayo Interview (5:14 min MP3)

Post Update: Here’s a picture of Brad’s car that he’s working on and it will be using ethanol.
