The fact that it was a visitor, not park officials, who spotted this, makes it even more appalling.
That structure could have been minutes from catastrophic failure... and the park didn't even notice the large, visibly widening crack.
@RationalLeft Well in fairness it is what we in the biz called a "hairline fracture". Oh wait, scratch that, it's a fracture you could see from the parking lot!
@MidnightRider And it was visibly flexing open as the passenger car went by.
@MidnightRider Hey, grey duct tape! Blends right in!
