So why did the fish cross the road?

The salmon has to be one of the most determined animals on Earth.

In ditch to the right you can see other fish waiting for the truck to pass before they cross.

I once witnessed a twelve inch rainbow trout swimming up an alpine brook that was maybe six inches wide and an inch deep, at about ten thousand feet in the Sierras. It was the middle of nowhere, little vegation, no other body of water in sight, and here comes this crazy fish. It just went splashing by, most of it's body out of the water, on it's way to who knows where.
