Beware of the windowless work van

I encountered a first on my bicycle commute to work a few days ago. I got something thrown at me. As of late I've been feeling a tad confrontational on the road. When I got honked at I'd give a stink eye or when a car would purposely gun past me without sharing the lane my tall finger would appear in all its glory. More times than not shouting match ensued and I was swerved at a few times. I decided that all I was achieving was an adrenaline rush and a sky high heart rate so I chilled out and went to my happy place and had a few weeks of zen commuting. The other day in a construction zone in the Loop I got zipped past by a work van. It scared the shit out of me and I gave in to a shouting match and was swerved at then while 2 lanes away a cardboard box was tossed out the passenger window and fell to the street. Really..? I'm going to get crap thrown at me. Ridiculous. Maybe a new route is in order to limit my Loop time travel.
