First remember that this is there home and they are use to the rain. If it is a light or medium rain they usually go about there business, my experiance. heavy rain, they hit fields or pine thickets to get out of it. Once the rain stop's like deer they are hot and heavy, I think best time to be out there. Only one thing keeps me from hunting in rain, if it loud enough that I cann't hear a gobble, they cann't hear me.
