You were lucky. I distinctly remember some non-union truckers who were shot to death from overpasses. One, in particular, was hauling a load of dynamite -- and the shot set off the load.
Nothing but a crater left on I-44.
I had a very close call as a non-union truck driver in the mid seventies when the union thugs shut down the highways around Chicago. A group came up to my truck and a couple of them wanted to bust my legs and arms. I was eighteen at the time and the leader of them let me go. There had been some shootings and other non-union guys beaten badly, so I felt quite lucky to escape without harm. To this day I have great hatred not only for unions and their thugs, but for the police and the state of Illinois that allowed this to happen without arresting any union thugs.
