This afternoon about 3:00 I was driving west on I90 out of Chicago. I was in the middle lane when I heard a couple horn blasts coming from behind on the left side. I thought maybe someone was trying to signal something was wrong with a vehicle but saw nothing. A couple minutes later more horn blasts and a blue Durango was in the left lane slightly behind me. A woman about early thirties had her window down and was flipping me off and screaming at me that I was a Mother******. No I hadn't cut them off, but I did give her a big smile. That made the driver speed up so they were next to me. I put my hands up and hollered WHY. She hollered Obama and signaled with hand signs (maybe gang signs), additional flipping off and the ever so friendly Mother******. I just smiled and waved, you see I had a Bumper sticker on my back window "NObama 2012" Yes she was a O supporter, maybe looking for more freebies? money for more putred green nail polish? who knows. For one thing I'm sure she was a prime canidate for the TSA at O'Hare airport.
