If you look at the license plate at the camp fire, you'd see that it was a North Carolina plate.
Looked up Wellington and it's in Florida. Unless you're talking about Wilmington in North Carolina? But I heard Christa say Wellington. Florida is just next to Georgia.
But you do raise a good point as Christa said they must keep heading north. But that doesn't make any sense why they'd say Wellington.
Good point. Still, Christa was talking about snow, and next episode takes place near a a ski slope. Even in the winter, snow in Florida is rare. Admittedly, you could say the same thing about North Carolina, but not quite as much.
