Much has to do with location...Some guys have a knack (or experience) of picking out a good spot...I doesn't matter how good you smell, shoot or look, if you aren't in the right location...Frankly some of my areas I have hunted for 25 years or so...I don't scout, why let the deer know I'm coming?? I know which way the wind needs to be coming from to hunt it, which direction to come in from, where they bed, food sources, etc...The first time you hunt a stand is the best time to kill a deer out of it...But, I am lucky as we own 3 family farms and I'm over 50...So it does get easier...Frankly I usually see deer when I go hunting...It might not be the one I'm hunting, but I usually see deer...Even if I don't, I usually see something interesting....One of my best hunts last year, I was entertained by 2 young coons in a white oak, not 15 yards away from me...
Another thing...If possible, learn to hunt before a weather front moves in, deer seem to be more active duting this time...
