So how accurate is the information about Centrailia PA? In the book there was a fire some 34 years ago (longer now) that is still smoldering. Is there still an underground fire that will burn for a thousands years. I really know nothing about this area, only what I read in the story/ account. I have been to the white mountains in NH and experienced the sudden weather changes. We were there in July and they were predicting snow flurries. You can really get caught off guard and unprepaired in that region.
