I see a lot more deer when the weather is poor. Up to a point that is. Rain I will hunt in but if it is and extended steady rain I may pass or downpouring.I also see deer in windy conditions, I just may prefer to stay on the ground as opposed to in the treetops. And I really like hunting in the snow. Right when a storm starts is best. And especially when one is going to be a doozy(a foot or more) the deer know it is coming and I will be looking for them in the pines. When it is calm and sunny I seem to see a lot of squirells but not deer.
