I'm at Bristol and listened to Kenny's frequency during the final practice.
It was really neat to hear how he was working with the crewchief and discussing what the car was doing and what changes they needed to make. They fixed the rear with only 1 or 2 changes and then went to work on the front. When time ran out Kenny said they were 75% of where they needed to be. Kenny was all professional and business and a pleasure to listen to.
Dale Jr. was interesting also but he was f____ing this and that with numerous other expletive's and was not happy with his car at all. I'm sure he'll get it worked out before the race is over though with all the cautions at Bristol.
I like and respect both drivers but you can sure tell the difference between old school vs new.
