My grandfather and his fishing buddies used to use the term blueback to describe cutthroat fishing as they purchased crawlers from him in Hoquiam during the mid 60s. He took me to the lower Chehalis to plunk with his favorite bait,sucker, a few times in the early summers . Another of his favorite haunts was the elusive blueback ,Sockeye salmon, that could be caught in an OP lake at that time. Razor clams, crawfish, with a crawler behind a ford fender trolled were the method then.
