I've decided that I'm no longer getting out of the way of bicyclists on the campus sidewalks unless they're going so fast they'll kill me.

You see, there's a bike path.
In addition, there's a road.

You're a vehicle; get the shit onto one or the other. It's the law, jackass.

Hit me and it ain't gonna be good for you. No, I won't start a fight, but I will wait for the cops to come with a ticket for you.
