Things are also designed so that in Disneyland you cannot see any structure outside of the park (although I think there might be some part where you can see some high-tension power lines). It was a mix of design and strong-arming the zoning commission of Anaheim.
That is a very impressive aspect. After reading about the sight lines at Disneyland however many years ago, I've started actively looking for them when I've visited. It's impressive what you can't see but know must be there (power lines, access tunnels, etc).
