Light rain or drizzle they like to be in the open fields. In a heavy down pour, they will move into cedars or an area the will give them some protection. The reasons they do that is for their protection, they only have two things that keep them alive, their eyes and ears. Even a light rain in a hardwoods makes hearing difficult, they can hear a lot better out in the open and can see movement better. In a down pour they try to protect their eyes as much as they can, we can look down to keep the rain out of our eyes they can't and they can't hear very well either so they will head for low heavy cover, cedars are just right for that, they can get under them and even tho it's a down pour it is still quieter in cedars then in a hardwoods and it offers some protection for their eyes.
