I didn't really know in what section to put it, but since Paris is my second home, I decided to post it in here.
For fun I've made a video showing all the four Big Thunder Mountains currently available in Disney parks around the world. And to my surprise, I noticed that all four were for the biggest part similar in track layout. Only Disneyland's version is build completely mirrored from the other three versions, however if you flip the video (like I did) you'll see the resemblance.
I hope you enjoy, and by the way; which one do you prefer?
