I did drive a big rig... once. It was a new product release and I got to drive it around the test track a few times. I was the finance manager for several product development programs for new trucks in foreign markets. Then I was the finance manager for a company supplying after market parts for heavy duty trucks. So to be kind and let BYU fans get their giggles I would say "I am in trucking".

Also, driving an unladen semi truck around a test track is really fun.
