For much of the year, it's too cold in Duluth to use their new $1,700 scooters to fight global warming

Here.

From the July 18, 2007 Mayor's Minute here:

The Ride to Work organization advocates and supports the use of motorcycles and scooters for transportation, and provides information about transportation riding to the public. On Wednesday, July 18 I rode a scooter donated by London Autobody to and from work in order to help limit my own contribution to global warming and promote Ride to Work Day. Compared to automobiles, scooters and motorcycles have a significantly reduced output of carbon monoxide and other gases which contribute to global warming. The use of motorcycles and scooters for transportation can have a significant impact in slowing global warming.

Ride to Work Day was a wonderful way to promote Earth-friendly means of transportation. However, Ride to Work day should not just be one day, it should be every day. Everyone has a responsibility to take steps to reduce their own contributions to global warming. You can ride to work on a motorcycle, scooter or bicycle. You can walk to work if you live close enough, or carpool with a friend. You can rollerblade or skateboard to work; or even ice skate to work in the winter time.
