^ Paint is expensive, especially Hulk Green. Nothing in the park matters anymore except Harry Potter and if there is any painting going on it will be for Harry only. Hulk is also protected now by DADT, so doesn't matter what anyone says. UOR believes that if the lack of paint on Hulk gives you the amusement of talking about it on here then it has succeeded as an "amusement" park. Rusting columns ups the feeling of danger and fear of riding, thereby enhancing the experience of the ride.
Finally, if the truth be told; there are no comptroller docs to do this work.
