I continue to be amazed by the IU students that blow through stops, don't wear helmets, ride on sidewalks, ride with dogs in their lap
I see the same thing at UofM and it boggles my mind. I'm sure it's the same on every campus, too, which is scary! Yesterday evening I was passed on the right by a bike going down a somewhat steep hill. It scared me that I didn't see him AT ALL before he passed, and I could have easily hit him if I had to park or turn or just move to the right a little!

It was dark, he had no helmet, and then he completely blew through a stoplight at the bottom of the hill. Luckily there were no cars coming when he made that left hand turn on red.

Boggles my mind, I tell you!
