Welcome to Western Washington Elk Hunting. For years, we had an area in Winston thick like you mentioned. Every year, we would chase a couple of herd around thru the same thick brush every single day. Then I finally said BS. I spent two weekends with a pruner and limb saw, in early spring, and pruned the bajeezus out of a few areas in this stuff. I opened up a couple of cooridors in the middle that no one else would be aware of. Then come fall, when the herds were milling around in the spot, we could sneak into the area, and push the herd by a shooter in the brush. Worked great, saw lots of cows! And that is no Bull. (No bull to shoot either...)
