I had a tour of Walt Disney Studios and it was very interesting ot learn that Walt Disney was not only an engineer when it came to animation but I also learned he was one in other areas too. He knew that there was much more than fun to developing Disneyland but also safety and fun. He put six pillars into the water tower in Disney studios. It is no longer used as a water tower but it is very structurally sound.
No one else planned for growth.
