Yeah... If I lived in CastleRock, I'd be hunting Blacktail in the Saint Helens area. Skamania... The biggest BT I ever saw come out of there. Or hell.. hunt BT in the Willipa hills and learn the area for Elk.
But if you want to hunt the Nooksack Elk herd some day.. Hunt BT by walkin in at the main gate at Cabin Creek road, Lyman. There's bucks up there. Be prepaired to put on the miles. Hunt it like you were going on a high buck hunt. Backpack or horse pack in. Sierra Pacific will not open the gates for you. Be prepared for RAIN.
