Light rain and drizzly days are my favorite time to hunt, you are much more likely to see deer all day. And while I usually only hunt from astand, the woods are very easy to sneak around for a stalk in light rain. If it's a freakin monsoon, I vote with the others stay home and stay dry. Pop up blinds keep you dry in light rain, and I have three tree houses to hunt out of, so it might be easier for me than some others. I also agree that you need better than average shots, go for a neck or high shoulder shot if you decide to shoot. Trackng is nearly impossible.
