Although the MK is much maligned for it's poor upkeep, it is actuallly turning out to be the keeper of the flame for many missed original Disneyland attractions:
Tom Sawyer Island (not Pirates Lair!)
Swiss Family Treehouse (also in Paris - which has the best version. Tokyo has it too)
Astro Orbiter (Rocket/Star Jets) still on top of platform accessed by the gantry
Country Bear Jamboree (well it was a MK original)
Carousel of Progress (or at least, the rotating theatre...since COP is supposedly moving to the Smithsonian)
CircleVision (okay, it's at EPCOT, not MK)
Frankly, I like that fact very much.
