Well now I am sad. Ignorance really is bliss.
True, but what never was cannot be considered as removed. All attractions start off as concept ideas and either engineering or accounting or both can weigh in and cancel any further discussion about that concept. It might have been thought of in someones mind and presented as an option, but would never be a lost attraction until it became a solid consideration and was scrapped at a later time.
Knowing it was thought of is a mixed blessing and it depends on our mind set whether or not it can be considered anything other then an idea that didn't hold its own. I think many times about the concept of going to the bank and finding out that some millionaire deposited a few of those millions in my account. Then I check my bank balance and see that it didn't happen. Disappointed sure, but it is very short lived because it never was to begin with. It was just a thought.
