Kayaking Down a Drainage Ditch

Kayaker Ben Marr took a trip down a drainage ditch, albeit a well-known sluice called Lions Bay Slide in British Columbia. I;m sure he was familiar with the route before filming this, but when seeing the POV version, I kept thinking about how suddenly a drainage ditch can turn into a culvert. Marr's entire ride is shown from a couple of different vantage points. He got up to 35 miles per hour! (via Daily Picks and Flicks)
