Used to hunt in rain because I would be out there regardless since I had limited time to hunt when I was younger. Hunted in it many, many times. Never shot one in the rain and wouldn't even see one on the vast majority of those days, never mind a legal one. Same with small game. Consequently, no hunting in the rain for me anymore, save myself some misery. I know some pretty good deer hunters, a few like the rain, many will sit it out especially if there is also a bit of wind which is often the case.
Can't kill'em from the couch, or bed, apparently I can't kill'em in the woods in the rain either.
Hate the rain.
