The Fall of 2010 brought the largest Sockeye Salmon Spawning Run
since 1913, estimated to be in excess of 20 million fish. These, part
of an estimated 7 to 8 million, have fought their way upstream
approximately 500 kms inland, to this part of the Southern Interior of B.C.

I have never seen anything like it before, except on TV where one
eventually sees everything if enough time is spent watching it.
