Once a month on Sundays, the city of Portland closes down certain neighborhoods to car traffic, opening up the streets to foot- and bike-traffic only. They call this Sunday Parkways.
It’s all very cool. It cuts down on cars, promotes other modes of transportation, promotes physical activity, gets families out on the streets of their neighborhood to have a good time. Today’s Sunday Parkway was an 8 mile loop. The parks within the loop all have activities and events, such as dancing, aerobics, music, bike obstacles, rock climbing, vendor booths, food, you name it.
