I have to go with lht here...while I don't know about the people he saw specifically, but when I started many moons ago in my field I was in installation. I drove a truck mounted crane that had a 28 foot flat bed truck, and a 22 foot tag along trailer.

I did that for 15 years. I have a load of respect for long haul drivers...you have no idea (unless you have done it) how hard it is to take those trucks through traffic
