I bow hunted from around 1991-2005, always up by Quartz Pass/Lofton Resevour, about 10 miles east of Bly Oregon. Gotten a number of deer there over the years. The population seems to be dropping the last few years, but I've always loved that area. Silver Lake is nice to, Rifle hunted there in 2008 and got a nice fork. Don't do much serious hunting on the west side.
There's a lot of public land and gated private timber (hike or bike in only) up the Skagit. We did lot of deer hunting up there while in College at WWU. Lot of deer, we never saw anything huge though. We were lazy and focused on clearcuts with a little more effort you might have better success that we did, two deer in four years between two hunters.
There can be too much of a good thing with antler rattling.
I like to hit the horns together for a good 30- to 40-second rattling sequence and then hang them up and resist the urge to hit them again.
This works to the hunter's advantage, because if a buck has heard it, he may have been 300 or 400 yards away and he comes in and he's not exactly sure where it came from.
When finally is time to rattle again throw a slight change-up into the routine.
The second time, don't rattle as loud...
