the Com m unity Cycling C enter is the
U nderstanding Barriers to Bicycling
project, which began in 2008 with a

both G raves and Tettah, the effort
has driven every program they have
created since.
The m ission was carried out by
first investigating the cultural and
transportation histories o f north and
northeast Portland and im proving the
organization’s ow n cultural com pe
tence, and then by reaching out to
