Program: Riding high on American white water

Adventure sports are a way for people to connect with the environment, often at its most extreme.

White water kayaking is one of those sports. It allows people to go to places sometimes inaccessible by road and track, to deep canyons carved out over millennia.

Kayaking rapids can be a lot of fun. But it can also be dangerous, and things do go wrong. This year in North America a number of well known kayakers have lost their lives doing what they love most.

Brendan King goes to the Pacific North West of the United States to speak to kayakers about how the river has changed their lives.
