If you think having to drive through a road construction zone is frustrating. Try doing it for 10 hours or so a day in one of these 100ft + long rigs. Five or six days a week all summer long. Eighteen speed transmission, dodging flaggers, cones, barrels, equipment, and workers. Getting in and out all day long while dodging frustrated drivers that HATE YOUR GUTS, and even try, sometimes, to get you in trouble. It's character building. Maybe not a pretty character, but character building none the less.
I just remembered I had these pics on my laptop. Two of the rigs I used to drive. The first two pics are of a bunch of us stuck on the highway waiting for a wreck to be cleared. One of ours and another 'oversized' rig that tried to navigate a sharp curve at the same time.
