I got up very early on Friday morning, much earlier than I normally do. I decided to go into work.
After I left the train station, and walked to my place of work, I stopped as cars were exiting the Eisenhower expressway to downtown.
In this case, they weren't your average cars, but were three trucks in a line, and looked very similar to this:
If it's not clear to you, the above picture is of a truck that is *not* pulling a container that can haul stuff. All that truck is pulling is a two-sided billboard.
I was witness to what I assume was the beginning of a long day of driving for these trucks. Their drivers were given the task of weaving through busy sections of Chicago to advertise -- that's it, just advertisement, for it's own sake.
I've always said increased traffic congestion, environmental pollution and dependence on foreign oil were signs of a great ad.
