Considering the world we live in where minor damage to anything can be escalated into "ThE sKy HaS fAlLeN!" in about 5 minutes is it any wonder Chessie would block off the area? All it takes is one errant photo of a burnt and blackened item and suddenly the news is filled with "Smiler operator park ablaze" headlines.
Fire brigade have been called to Chessie a number of times. The amount of incidents that don't get documented is amusing (in a morbid way).
