could shut them down...but ive seen alot of odd things in the turkey woods...seen them shut down on beautiful days and hammer on pretty nasty days...only way i know to tell is to go hunting and find out....some of my best hunts have been on cold wet days...made me wish i was at home under the covers still....till they started hammering and coming in on a string...then you dont even realize its raining or you were shivering 15 minutes earlier!!
