I've got an old elevated shooting house on one of the properties I hunt that has no windows. Had a ton of wasps too. If it was just me hunting I wouldn't mind not having something but I'll be using it to take my woman and my nieces and nephews to hunt from so it's a little more comfortable. And you know how kids like to move around.

What is something I could get for cheap to put over the windows to conceal us a little better but still be able to see pretty good out of it. And keep the birds and bugs out in the off season.
