I'm originally from Kennewick. Head up north to the Okanogan highlands area and also try around Newport. Alota deer around the Dimond lake area. I was a camp counselor at Camp Cowles BSA in 97 seen more deer that summer than I ever have. Also got moose around there.
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
