My first week of commuting is nearly over. So far, it is great. I get to work in a much better mood, and find myself in a better mood when I get home, due to the exercise. It is also a LOT more fun than sitting in traffic. I've also been getting lots of comments from people at work that see me roll into the parking garage...I'm the only bike commuter in my building right now (several hundred people).

Weather is great for now too, 60's in the morning and when I lave work (10-11 hr days this week...). I'm sure that will change as fall/winter really rolls around.
