RE: It's all you'll ever need
killed a spike, a 4x5, a 6x5, a 5X5, another 6x5 ..... I remember killing one and not finding him one year, and 2-3 years I didn't get opportunity, I missed on shots 1-2 years, chose not to shoot (muzz tags) a couple of years ......... I've had really good success elk hunting. Not so much the last 3-4 times I've went, partially due to a new outfitter liking the same place I do, partially because I have hunted with a longbow. One year wasa disaster from the git go !
Thermals are true - sometimes. Prevalent winds are prevalent ....... sometimes. I swear stinking like campfire is THE best cover scent, bar none.
Whitetail hunting, diesel and cattle poop is the best coverscent I think.
