Not sure why this never occurred to me before, but I think (fear?) we're answering our oft-asked question of why WDFW seems to favor boat fisheries over bank fisheries, right here, in this very discussion:

Bringing the boat means you're injecting more money into those aforementioned local economies (in more markets, too) than bank walking. More money for the gubmint, too, cause you have to register your boat and trailer EVERY YEAR. I bet
that explains why they like their anglers in boats so much....
