Which classic Disneyland attraction was NOT running on opening day in 1955?

One of my favorite parts of Disneyland is that you can still get those opening day vibes, especially when you visit some of the old-school rides that have preserved much of their original charm — even after decades of refurbishments and small updates.

There are some truly iconic attractions that have been there literally since day one — you'd think this was one of them, but you're dead wrong. Which one was NOT there on that fateful day in July of 1955?
