Keeping The Park Clean
Because he spent so much time and energy making Disneyland the best it could possibly be, Walt Disney knew that he wanted to keep the whole thing spotless. To do this, he knew that he needed to stop people from throwing their trash on the floor and dirtying the place up.
Yet, how was he going to do that? As a man who liked getting his hands dirty, Walt decided to do his own research. He followed guests around the park, and he looked into their habits.
It was here that he realized that people would hold their trash for around 30 feet before throwing it on the ground. Because of this, he knew exactly what he had to do. Today, you will never be more than 30 feet away from the nearest trash can, which means that you can dispose of your trash easily and without much effort.
