Pedal Pusher - NYTimes.com Earl Blumenauer (above), who represents most of Portland, Ore., in Congress, insists that Washington, D.C., is a bikeable town. But then, Blumenauer would insist every city is a bikeable town. A passionate advocate of cycling, he founded the 170-member Congressional Bike Caucus and led a successful charge to put bike lanes up the middle of Pennsylvania Avenue. He bikes to work on Capitol Hill most days, and to the White House, occasionally confusing security guards. Blumenauer suggests visitors make good use of the city's bike-share program, Capital Bikeshare, or rent a bike from the Bikestation at Union Station. He also recommends riding on the Capital Crescent Trail; along the C&O Canal; on the upper Rock Creek Trail; and at the National Arboretum, "a secret gem."
