Austin was under fog for most of Sunday night into Tuesday morning, and a lot of people were thinking about dementors, "The Walking Dead," Stephen King and  "Stranger Things" as they posted their foggy photos to social media. Take a look and see what people were saying about the foggy weather that started off the week:
