I have had the same expieriance. this last year I had it set up in a rock pile in the midle of a field. when looking from across the field, I had a hard time seeing it. But sure enough about 1/2 hr before dark some deer came out of the woods and just stood there on high alert staring at me. would not come close. I was down wind so I know they didnt smell me.The few times I've tried one it did not go well. Of course I had only set it up 3 weeks ahead of time. It's a scent containment blind also. The deer I did see never came close, they stood there at the edge of the tree line until dark just standing there looking at it. I was in the woods across an opening about 35 yrds across.
This is what I have found out to! Deer will tend to shy away from a "new" or forign object at first. If left up for a week or so they will get "used to it"..But if you place in some natural cover ie..brush, grass, etc. you will increase your odds. I have done the put up that morning and hunt that evening, but I stuffed the blind under a tree that was surrounded by brush and it worked, but I was basically using a natural ground blind that was already there..I would prefer a tree stand over ground blind but with a stand you need....well a tree??:shade:You can set it up for a morning or evening hunt but you will have to brush it in extremly well, deer do not like blinds, from my experiance they will avoid them if they can see them.
