Nice first post! ^ Welcome to the forum!

What would someone accomplish by trying to steal a bike from a moving cyclist? It's almost moot; it would be nearly impossible to accomplish.

The commute was good today. I saw my teacher who also cycle-commutes to school on my ride in. He was riding to the back door of school, and there's a bit of a ledge to get on the driveway that goes past the back door of the school. I saw him in the distance doing a bunny hop (on a road bike, mind you) over the ledge at approximately 20mph--I guess he's daring! When I saw him, I was locking my bike up at the bike racks (at the front of school). He takes his bike into school and keeps it in his office.
