why didn't he shoot the deer?

I hate hearing about guys "seeing" monster bucks etc..or screwing up the hunt.
My story is always never see a shooter, or never get a shot, not "missed"

What's your secret to keeping the poachers away? Wish I hunted property I knew was only hunted by me, and not poached or even trespassed on. What's with random people walking on private property? horseback riders etc...? hikers/dogs...
