Gary, IMO Eastman magazines are very informative and educational. The member sections is great for assisting in draw systems and sharing information on good draw areas. They also have some great hunting books on the market.
I have grown up eating and sleeping Eastman books,magizines, and videos. I have worn out 3 of the "old" Eastman videos. Most were on hunting the high country for sheep when Mike was a kid like my self. Mostly Alaska and some Canadian Rockies for Stone sheep. Man what I wouldn't give to go back to those times. I have prolly learned more from those videos then anything else. Fair chase hunting is the way to go.
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...
