I think he is at some type of range, just guessing of course. On his tee shirt right shoulder is a patch of some kind. He's probably right handed, his forearm is bigger on the right side. I was a bus driver and wore my watch on my left wrist so I could keep my right hand on the steering wheel at all times, yet be able to glance at my watch. So there may be an unknown reason for this.
There must be some logical or logical reason to him for that rig. I cannot think of one though.
Looking at his pants it doesn't look very comfortable, if the front is like the back his balls are getting strangled.
It could be a temporary thing he did for some reason? I can't think of one.
I really do wish this guy would see this and respond. As Ricky would say "you got some splainin to do."
