RE: deer movement and fog.
The deer move around here really good in the fog. The problem is your visibility is limited. When it's foggy I go walking. Most deer won't run at noise alone. As long as they don't smell you they will wait to see what you are if they hear you coming. I've killed many bucks by walking up on them and shooting. Foggy weather is a great time to kill deer if you know how to do it.
