This Friday, Saturday and Sunday (September 19-21, 2008) is Free Bike and Kite Weekend at Governors Island in New York. With help from Transportation Alternatives, Governors Island visitors can borrow a bike this weekend for up to an hour.
Crazy things happen when you offer people free bike rides on car-free streets. People who haven't ridden in decades get on and roll away, grandmas get on bikes, little kids learn to ride, world peace, etc.
The first 250 visitors each day this weekend will also be given a free kite to fly on the Island’s Parade Ground.
Streetfilms (naturally) has a video on Free Bike Days at Governors Island.
