Wintery Bay

 is one of the many obstacles found on The Road. Unlike the other hazards, Wintery Bay cannot be driven to ⁠— nor does it seem to physically exist — but its name is provided by another obstacle (via The Hitchhiker). People who hear it somehow know where to go to find Wintery Bay. And once someone arrives at a specific destination, the person disintegrates into dust and fade away, or as Bonnie puts it, "move to Wintery Bay".
