Last week, the League of American Bicyclists announced the most recent additions to the ranks of Bicycle Friendly Communities, which means this StreetsWiki entry is ripe for an update:
The Bicycle-Friendly Communities Campaign is an awards program administered by the
League of American Bicyclists
that recognizes municipalities actively supporting bicycling. 
Cities wishing to be designated a Bicycle-Friendly Community complete
an application which covers bicycling facilities as well as related
traffic enforcement, promotion of bicycling, and education of
bicyclists and drivers to create a better environment for bicycling.
The League of American Bicyclists recognizes newly
designated Bicycle Friendly Communities with an awards ceremony, a
Bicycle-Friendly Community road sign, and a formal press announcement.
As of May 2008, only two communities — Davis, California, and
Portland, Oregon — had received a platinum rating, the highest
available. There were 82 cities designated gold, silver, or bronze. A
total of 212 communities had applied for BFC designation since the
program’s inception in 2003.
If, like me, you’re curious about how Boulder has become a great biking town, stay tuned to Streetfilms. Clarence Eckerson is on location this very moment, gathering footage and interviews to tell the story.
