It seems Disneyland has started removing the french fry rocks from the entrance of Tomorrowland.
Like TROR said earlier I have only ever known Tomorrowland with the rocks but unlike him as of now I am kinda sad seeing them go, at least right now without having any sort of Tomorrowland revision confirmed it is going to feel empty to me personally. I know some people (probably most) are glad they are going to be gone but for me, until they just change the land itself as well, I am going to personally feel like there is a hole there and that it is going to be very plain looking for the time being.
I've never known a Tomorrowland without them yet they've never defined Tomorrowland to me. I feel like I should be disappointed in seeing them go, and who knows, maybe I'll prefer it with the rocks once I see them gone, but I'm hopeful for what Tomorrowland has in store. I want to believe good things are coming.
