It's the most obvious thing in the world, but I've only just connected the two thanks to your post. How did I miss it? I mean, really... HOW?
Now, I'm really curious as to how SM evolved and if there was any "awkwardness".
It was pre-internetz so back in the day, things would just show up at a theme or amusement park. I still remember when BTMRR was a big deal in my teen years. We knew some type of western roller coaster thing was being built, but that was it. No discussions. I'm also reasonably sure that during that time Disney didn't poll guests about everything. Or if they did, it was a lot less frequent.
