Shot a 12 point 2 years ago in the rain. I made up my mind to hunt this feeder all day long. Right after I got there it started raining and was pretty cold. Got out of the high rack and into my truck. It was about 1 pm when the deer started moving. If it's just a light drizzle, I would stick it out. More than that, I'm probably taking it to the house, deer moving or not.
