I've killed a schit load of deer in the rain. It kinda sucks because the rain is loud and the deer are quiet. When I was younger and didn't have any money, I just got soaking wet. Now, I wear a full rain suit and use a tree stand umbrella. Those umbrellas are worth their weight in gold. Light to moderate rain is good. But if it's a torrential downpour, I think the deer hang low. It's when it quits being a down pour and the front moves through is when they'll get up and move also. Light to moderate rain is sort of peaceful and a lot of good deer can be had especially if it's the rut.
