At both the colleges where I teach, a decent fraction of the faculty are bike commuters. One campus is at the top of a pretty decent hill (800 feet elevation over two or three miles). Back when I still commuted by car, I was astounded at all the gray-haired professors who made that "impossible" (as I perceived it then) climb on their bikes each morning.

In fact, their example is probably a big part of what got me into bike commuting.
