I was worried about ths as well, so I leave the windows I'll be shooting out of open even when I'm not there so the deer will be used to it that way. Worked twice so far this year. Even had 2 turkeys wthin 5 yards or so & they never saw me in there. One thing I might mention is you should practice shooting from your blind before you hunt from it. Then you could test your mechanicals. I practiced from mine & found it easy with the windows down 4" or so. Then thursday afternoon I shot right thru my window! [:'(] Still got the deer but hit it around 6" back from where I was aiming. I didnt notice till I was closing it up to recover my deer & there were 2 nice holes thru my window. Figure I'll leave it down a bit more from here on in.
