I choose to go out even when warm knowing many who have filled freezers and decked out walls with good Bucks during hot weather. It is harder but still can be productive every once in a while. I limit the distance and time I spend getting to a spot and how long I'm out in it. So I go out and hour and a half before sunset and get out of the woods before the morning gets to hot. It is a pain washing my gear more but thats hunting and like my Buddy says you can't shoot one sitting on the couch in the AC.
