Welcome to the BGH Vanguard! Looks like you already found Numbnutz. He is one of the most knowledgeable guys we've got on the northwest region. Good luck on your hunt and we wanna hear the story of your success when you're done.
Vanguard, hows your scouting going? Give you an update, archery season was very slow. not sure why. We did get into a couple bulls but over all it was very very slow. hopefully you are having some better luck. like i said before if your hunting late things should be better for you as the elk wil be in bigger herds and at lower elevations. let me know how your doing and if i can help out anymore.
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...
