I hunt in the rain. If your hunting whitetails during the rut, your crazy if you don't try. I have Mad Dog Growler rain gear I wear to the stand. Once there I use a Port-a-Roof for even more protection.

One point to consider: A great time to hunt is after a rain (bucks refreshening scrapes). Lots of people will go out and hunt. The forest floor is still wet usually for hours after the rain. Blood trailing is just as tricky!!!
