I usually use open sights for deer but a simple LP VX2 3-9 would suit you fine for deer here. I've shot 3 deer over 150 yards, 20 between 7yds-100. If you were hunting Eastern WA, the Vortex would be a good scope.

I have a Vortex Viper PST EBR-1 MRAD 6-24x50. Great scope, very clear, excellent warranty. Shoots well out to 600 and beyond. Tried using the rifle it sits on one day for early season bear, way too much scope for yardages under 50 yards. Not bad for a clear-cut rifle, but I would pack a second rifle for the timber and brush if I were you.
