I do the majority of my ML & rifle hunting out of a blind! One thing I've learned about them is to only open the zipper windows as much as you need to get a good view. If you open them to much, it's about like jus twitting on the ground in the open. Also keep window at your back closed or just barely open enough to peek through if needed. You can get away with a little more movement in your blind if you do this. At least that's my experience.
