The colville national forest is thick and the elk are scarce but some of the locals have them figured out and seem to score consistently. if youre looking for meat only apply for cow tags in any of the yakima area units such as bethel, bumping, nile, or cowiche should draw every coupla years and have a good shot at killing an elk
if ya could afford it, i'd buy an idaho tag and head into the panhandle units. you are close enough to scout those areas quite well. its thick, but there are animals there.
I prefer Colville because I like the idea of a quick drive up either 2 or 395. I live on the north side of Spokane.
