It's been a long time since I hunted the Gila and have never hunted 16b.
This year I did put in. 16B is a big unit and there are no roads so horses help but there are many people who have killed big bulls without horses.
As you may know the there was a big fire last summer.
My plan A was to have someone pack me in as close to the eastern edge of the burn area as possible. If the rains come in this summer it should green up nice and the elk should be there fattening up.
Plan B was to come in from the north and bivy hunt. I wanted to cover as much ground as possible and hopefully get into elk. The place I had decide on parking was call indian creek if I remember correctly.
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...
