my guess is it's to protect the kings that run through 8-2 to the stilly since they are the main driver of a lot of the closures.
I am saying this because the amount of uninformed idiots who keep small chinook and think they are pinks is ASTOUNDING.
Seriously. but then id be giving WDFW too much credit for thinking of something smart.
2 years ago the amount of guys i saw showing up and pulling their "pinks" out to show off to the counter, that were in fact juvenile chinook was disgusting.
