Rain's great
Deer DO NOT stay put when it's raining. That's a myth. Do you think if it's raining, they go into their living room, sit on the couch and watch football?
Deer are out there every day. They do not think like people and they will eat and move around, possibly more in the rain.
Another benefit is it means less competition in the woods. If you’ve got a good spot or two and done your homework, you are in great shape. The hardest part is warm and staying dry. Good clothes and a tree umbrella can get you in the right place at the right time. If you have a zip up suit, scotch guard it at the beginning of the season and it will be like a wetsuit. Once it dries, place in a plastic container with a earth scent wafer.
