"Carts of Darkness" is a Canadian documentary film (57') with an awesome photography telling a very human story. Murray Siple was snow boarding all the time until he had an accident who confined him on a wheel chair. He belongs to a wealthy family of North Vancouver but felt uncomfortable among his peers and found a bunch of new friends with whom he was able to share his passion for freedom and speed: homeless people who are picking up bottles and cans to make a living. They invented an urban x-treme sport: sliding down the hills using a shopping cart. Siple got completely into this group of guys, accompanied them in their problems and struggles for many months and eventually tried to help them to get out of their alcoholic problems. That is the cheesy part. But the rest is about freedom and speed and living according about your own 'rules'.
