I think it's mainly the amount of disturbance and the effects of the rut cycle during the rut.
I hunt alone, I don't talk in the woods (easy when you're alone), I don't touch anything with bare hands, I don't pee around my stands, I wear rubber boots that never get worn around gas stations, etc...don't know if any of that helps but I'm afraid to change the approach.
I sat on one of my stands outside a clearcut during the 2005 rut and shot a buck at 7:00am...dragged it to my stand, cleaned & reloaded the Flintlock, had hardly gotten settled back down and shot a second buck coming through at 7:30.
Conversely I've sat the same stands and not seen a shooter for days...have to remember that during the fall, Does & Bucks visibility ebb and flow based on which days they're back in the thickets breeding...then there are the days they're back in the woods cruising for does, etc...so it's not always the stand location itself, but the availability of cruising deer on any given day too
