No, no way, you don't walk around the office in your bike clothes (dripping sweat in the summer), and you've got too much leeway in routing.

On the "Yeah, sure" front I got a nice round trip in this morning (as I have been most mornings), and this one went within 3-4 miles of my office. I usually prefer to go the other direction, out into the country for a third to a half of the round trip distance -- it's a lot nicer than suburban riding!
