all depends on how much the wife is complaining.
I have cloths to help stay warm. if its a windy day I will set in the ground blind at the bottom of a ridge or atleast over half way down it. most of the time that elimanates most to all the wind. as far as temp I dont know the coldest I've been hunting in but here in Kentucky temp in the teens is about the lowest it gets and thats at night. the only times I can say I've flat out been cold I got wet. snow melting, rain or what ever but I was wet might have just been my hands or my butt from seat pad in stand, but wet to me is misarable.
