I am constructing a couple of new single man box blinds. None of my existing boxes have closable windows and I want these to have them to keep out the weather and critters. Since I have never hunted out of a blind with actual see through windows I guess my question is do you usually keep the window, if glass, closed while hunting or keep them open. Closed it will require more movement and time to get them open to shoot and open will let scent out, which is one reason I want windows.I am really just trying to decide if it is worth the cost to get something like the Deer View or just have a solid covering for the opening that can be shut when not hunting.
