RE: What is the biggest problem you face?
Just being in the tree I pick at the right time. Twice late last season I had a good size buck(judging by tracks and rubs he left behind) pass within 15 yards of the tree I was hunting out of. The first time couldn't have been more then a couple of hours before I arrived at camp. The second was two days later when another good buck and two does (again judging by tracks) passed by my stand while I was stalking a fresh track I had cut on the way to my climber. Later that day when I went to retrive my climber there were those 3 sets of fresh tracks and the "buck" track walked right up to my rush creek deer lure I was spraying out of a spray bottle(could see the brown urine on the snow).
Finding a productive tree isn't hard. Being there at the right time can be. The silver lining is I found another prime stand location while stalking the buck. It didn't help last year but should be a productive stand this fall.
