     Many Americans have been leaving their cars at home and riding to work on bicycles. Andy Clark
is the leader of the League of American Bicyclists. His group supports bicycling for fun, fitness and
transportation.
     Clark says this is good news for the environment. He says riding a bicycle to work does not burn
fossil fuel or creates dangerous pollution. Experts say the effects are the most important on short trips.
Shorter car trips give out more pollution into the air for each kilometer drive. This is because the car
engine will give out the harmful gas when it warms up before it can work well.
     James, a member of Congress, is a strong supporter of bicycle use. He says cities, counties, state
governments and state highway transportation agencies are planning the roadways of the future. They
are creating roads and paths for bicycles in cities and between communities.
     Last year, Portland, the Pacific Northwest city in the state of Oregon, had the highest percentage
of bicycle users in the United States. Portland has been doing progressive city planning for many years
to create special paths for bike riders.
