Second Sunday is an event I learned about when I attended a 2010 Memorial Day event in Lexington, KY where more than 2,500 bicyclists of all ages participated: http://tomeblen.bloginky.com/2010/05/31/cyclists-of-all-ages-take-to-streets...

Lexington has a Second Sunday event every month: http://www.2ndsundayky.com/2nd-sunday-lexington.htm

This state endorsed program just started in 2009, and is already reaping amazing benefits.
