Uh, Texplorer, the question was "What are your favorite Pitches in the PNW". A favorite can only be at the crags you have climbed at. So here are my biases (I'm from the east side of the state and Im Marty, not FAt Kid. He just uses my computer).

Vantage: That M&M's route that keeps getting bolted then chopped, Boschido, The routes around the Powerhouse that I can't remember the names
Minnehaha: Dihedral, Hooker, Hot Licks
Deep Creek: Motley Crux, Quiver, Opiate for the People
China Bend: Blue Chunks, Pork Sausage, Shut out

Metaline FAlls: Gunshow, Conan the Barbarian, 12GA. Pump
Riggins: So Thin So Fat, Tractor Boy, Brother Speed

My 2cents concerning PNW pitches. Spokane is part of the PNW isn't it?
