For illustrative purposes. Assuming you really enjoy salmon. Would you rather consume fresh, off the boat, wild-caught king salmon from pristine waters? Or, a salmon at the end of it's life-span, after making a successful spawning run?
For further illustrative purposes. Assume your Shining City DAC can be located in those pristine waters with schools of free swimming king salmon (no fishing boats in sight).
OR said Shining City DAC can be located at the end of the spawning run waiting for spent, successful salmon.
Hint: before you think its only about the salmon...stop yourself.
