Yesterday I used my road bike (Trek 520) to commute. It was a little faster (I don't worry about speed) but I prefer my MTB for the few rough sections through industrial areas. Did hit 32mph on a short downhill.
The greatest thing has been the short-lived break in the weather. Morning lows in the 60s and afternoon highs in the 80s.
Alas, it will soon come to an end.
