Good call Zipperman! I have hunted in many states, and in many different weather conditions, and rain has little, if any, affect on turkeys. Keep in mind, I'm not talking about very severe weather such as heavy thunderstorms, lightning, and very high winds. In fact, it has been my experience that rain has a tendency to remove insect life from trees, and I've witnessed many turkeys gathering beneath trees where the vegetation is limited to have a feast.
GOOD LUCK, GOD BLESS and STAY SAFE
