I live in Washington and I never heard of a Le Bam lol, nor did I know centralia was a town in my state as well. I thought that was the Centralia from Pennsylvania
Apparently the real town is spelled Lebam (without the space), but for some reason in the game it's Le Bam. Population was 160 in 2010, so no shocker that people haven't heard of it. As for Centralia, yeah, PA was the other primary candidate, but I decided to mark it as WA because that one's not a ghost town.
