I forgot to mention:
Last Thursday, I was walking across campus returning from a meeting, and I saw two bikes collide head on! They actually hit right in the middle of their front tires. Neither was going very fast, and while both came off the seats, they didn’t fall down. One of the guys was just surprised, but the 2nd guy yelled at the first.
I watched it take place in what seemed like slow motion, and I couldn’t believe that it happened. I think that there was some girl watching involved.
My colleague and I were cracking up and got dirty looks from the victims.
