I have seen salmon swimming upstream to spawn even with their eyes pecked out. Even as they are dying, as their flesh is falling away from their spines, I have seen salmon fighting to protect their nests. I have seen them push up creeks so small that they rammed themselves across the gravel. I have seen them swim upstream with huge chunks bitten out of their bodies by bears. Salmon are incredibly driven to spawn. They will not give up. This gives me hope.
