Join the celebrations on the last Friday of every month! People throughout the Boston area and other parts of MA, NH, ME and beyond are doing it! Just use green transportation that day: commuting by bike (of course) is great, but going by foot, bus, or train - even carpooling and walking part way - count! If you wear something green to show your support, you can also get discounts and freebies from an ever-growing list of sponsoring businesses throughout the region. For more information, and to register your company in Walk/Ride Day friendly competitions including a year-long Cambridge, MA mayor's challenge, visit http://gogreenstreets.org/.
