First of all, an apology for the quality of these pics. I probably should have taken a decent camera with me, but when you're in a working environment you kind of feel guilty about snapping pics of the stars in a quiet moment. So I never used flash, and the rooms or garages where the drivers congregate are always starkly lit, making photography from any angle tricky. That's especially true when trying to be a bit subtle, and when using an iPhone.
But still, not many people get to see drivers just before they get on the truck to do their parade lap, so I offer these as a sample. Let me know if the series is worth continuing.
