I was in coal harbour one day last year and spent a while watching one of the sea planes taxi and take off.
At one point it had started gaining speed to take off but had to cancel at the last minute because someone in a kayak drifted in front of it so it turned around and had to do the whole thing again. There were tons of other craft out on the water too, and I found it kind of crazy that it's being used as an airport considering how busy and chaotic it seems to be.
