RE: GROUND BLIND HUNTING
I've had about the same experiences that Retrieverman has , once in awhile they'll get nervous about "the new object" , but they usually just stamp their hoof a few times and then settle down when "it" doesn't move . I could have reached out the window and touched them on several occasions . A more permanent type ground blind such as a box blind should be placed well ahead of the season opener so they have a chance to get used to it , when using a pop-up I try to locate it just inside the tree line so that it blends with the background . You can also just rough it and set up in a downed tree's branches or a clump of bushes or cluster of boulders .
