Will the Upside Down ever affect anyone outside of Hawkins? Or anyone in Hawkins who doesn't already know about it?

"Stranger Things 2." Netflix

"Stranger Things" is at its best when the events and the characters are confined to the town of Hawkins, Indiana. At this point, Hawkins appears to be the only town in the world affected by these supernatural events. And, more specifically, the people affected by them seem to be the ones who know about it, or the people close to them.

Bob sacrifices himself the the demodogs (or stupidly just stands there when he knew he was being hunted), but he knew about the Upside Down for at least a day, and was dating Joyce Byers, who knew about it.

We also see the tunnels affect farmers in the area. But at what point does the very dangerous Upside Down become an actual life or death threat to other people outside of the main cast? For the threat to feel believable, it will have to grow moving forward.
