Flossing= "fishing" with a 4 to 6 foot leader between your weight and small corkie or just yarn and large hook. Then, cast out, slide your line across the bottom until you feel a fish and yank, hoping the hook lands in the corner of the mouth or anywhere on the head. It is glorified snagging.

nookie= King salmon, or getting it in the sack.

The carbon is a similar fishery, but worse than the Samish. I'd call Auburn Sports and Marine for more info on rivers down there.
