RE: Deer scent used by Indians
You can't really compare hunting 100's of years ago to hunting in the modern world. There was no were near the pressure on deer at that time, and most likely the numbers in a specific area were lower and the range of the deer much larger (more land, less people). Also they didn't have rules, regulations or seasons. If you were hungry you killed something. They could trap them, snare them, drive them off a cliff, chase them down on a horse, whatever it took to eat. They didn't do it for sport or the challenge.
Heck 50 years ago or so you didn't even need to wear camo or use cover scents. Just go out in a pair of jeans and flannel coat, or your carharts.
Thats my opinion any way.
