I was traveling on I-35 S coming home from Duluth, MN. I decided to take Scanlon exit and stopped at a yield sign to make sure I wouldn't collide with any incoming traffic. I was honked at and passed by an angry man driving a red truck with commercial roofing, inc. written on the side of his door. Mad, I flicked this man off and boy was it a bad idea! We passed the intersection and made our way up the bridge and this man slammed completely on his brakes TO THE POINT THAT I ALMOST HIT HIM. He immediately got out of his truck to yell at me despite the fact that he was holding up traffic. Right after an intersection at that.. I immediately took out my camera to record the incident after I called the cops. Before the angry man jumped back into his work truck he screamed, "GO BACK TO THE REZ!" and left the scene.. I haven't experienced that type of Road Rage ever in my life and I can't remember the last time i've been racially profiled either. However, i did learned my lesson. I know that I was in the wrong for giving into the negative behavior and flicking him off. However, his actions followed by mine were extreme. Especially given the fact that this man was acting like that while representing his company. Im 24 years old and he should've been the bigger person given the circumstances. I have told all of my friends about the incident and I also reported the incident to the Better Business Bureau. I find this type of behavior disturbing to say the least and I will do everything I can to share my experience with others. I Hope that another person doesn't have to go through this experience again. If someone can go that far, you wonder how much further they can go..
