Hands down a Ghost Blind. Zip tie two together and you are 360 degree golden. Best part is you can move it around daily to reposition without alerting the deer. Otherwise would be vulnerable to detection with anything else. I use mine during turkey season for edgy late-season Wisconsin toms. I'm invisible. Nuff said.
speaking of cold.That's the downside to the ghost blind. Especially if you have kids along. With an enclosed blind you can run a heater and stay warm.
