In an interesting bit of news yesterday, the California division of OSHA served notice on Disneyland and shuttered several attractions for violations related to worker (not guest) safety.
In addition, there was apparently a fire aboard one of the Nemo subs (also mentioned in the above article). If you’re planning to visit Disneyland (and California Adventure) in the near future, be advised that some of your favorite attractions might not be available.
