i like ground blind hunts..hey gerg since you know so much about them lets say you have three good openings....two right next to eachtoher at about 10 and 1 o clock and then you have another at about 7 oclock what would you use to cover it to keep it darker inside the blind?cus i know that the double bull has like a 180 view to keep it darker inside but what if you wanted and opening at 7 oclock?would you just get a camo cover for it or what?
