http://www.StreamDirectTV.up.to - MADHATNEWS! The US city of Portland in Oregon is home to a unique weekly cycling event known as zoobombing. It attracts an eclectic crowd of cycling enthusiasts who like nothing more than hurtling down a steep hill at high speed, on souped up children's bikes, late at night.

Some of the bikes are left chained up in a pile in the city centre, which has itself become a local landmark. The ride, often repeated several times in an evening, starts with a journey on Portland's light rail system then a hike to the top of a hill, near the city's zoo.
