Hi Darren,
Probably my aircraft background pushes me to be neat and clean. 26 years in aviation and we aren't allowed to be sloppy. We are in an environment where you constantly clean up before-during-after the job so it becomes standard practice. Plus for the past 15 years I've been an instructor - and we have to constantly remind people in class and out in the hangar and shops to do the same.
Lived here in INDY my whole life and have been into the Indy/Usac/NHRA deal since I was very young. I live just down the road from all the small and big race shops - and they are clean as can be. Some of the F1/Indy/Nascar shops are nicer then the inside of most peoples homes. Check out Ganassi Racing some time to see what I mean. They are a block from where I work at the airport and it's unbelievable the conditions of the current professional shops out there.
Plus the garage is attached to my house - so the wife wouldn't appreciate tracking all that inside ....
Jim
