I was impressed with how many cyclists I saw in Albuquerque this morning. Some were obviously just out for an early ride, but a surprising number appeared to be actually commuting (assuming people don't go on recreational rides with all that gear!) Plenty of volunteers at the table, but even more cyclists - some faces I see regularly on the MUP, and some that I haven't seen before.
Even if it gets someone out of a car for one day a year, I don't see how Bike To Work Day could be anything but good.
