I saw 3 bucks in a field on the last day of turkey season. It was pouring down rain so I went to the fields to see if the turkeys went out there. No turkeys but, I got to within 30 yards of 3 bucks 1 small, 1 medium, and 1 grande!
Thier hair is a different color this time of year. They had a reddish tint to them.
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...
