I was walking along my usual route from organic chemistry to my chemical engineering class, when I noticed snipers on the roof of Vet Med and a small crowd gathering across the street. A couple of people had signs, but most of the people seemed like they stumbled upon the scene by chance like me. I figured that meant that the President was inside and possibly coming out soon, so I decided to stop walking and join the group of people. After all, I still had plenty of time until class started.
I stood there for a while in the freezing cold talking to some of my classmates when some flashing lights turned on. It was so cold that my phone kept on turning off, so I got only one picture of the scene before any of the action started. A procession of cars started to drive out, but not through the exit that I thought they would be using. I ran over to the exit they actually were using and walked up a small snow bank from which I waved to the procession. There were two official-looking black cars, and in the second one I saw an older-looking man sitting in the back left window seat. Sitting next to him was another man, but I couldn't see his face from the angle I was at. Also, it was pretty difficult to see through the glass of the car windows. According to one of my classmates who was at another position in the crowd, that man was the President and he was waving to the onlookers.
After a lot of cars drove by, it was all over. I just walked to my next class like usual and I made it there right on time. It was a little disappointing that I couldn't get a good view of him, but hey, I was about 20 ft from the President of the United States!
