Dave,

Assuming it's Snoqualmie that you're coming over, you'll drive right over the Green (Hwy 18) in prime fishing territory. Also, as Osprey mentioned, you'll only be a few minutes from good spots on the Puyallup. Other choices put you out over a half hour's drive from your route to get to fishable water, which may be a consideration, depending how long that half day is.

Good luck!

Sincerely,

Salmo g.
