I have shot my biggest deer in the rain. I'll sit out all day no problem. Rain in my neck of the woods gets deer moving while wimpy hunters head for the inside.
A plastic bag makes way, way too much noise in the rain. Tried it and wouldn't recommend it to anyone.
I hope you don't gut shoot your animal or hit it other places then the vitals. I don't care who you/we are, our arrows don't always go where there suppose to! Good luck with tracking that in the rain.
