There's several places where you can see the Mummy coaster track (the end of the ride where the "giant head" shoots fog at you is a great example...look to the right and you'll see the sharp turn you take before coming into the fake ride station), and when the ride is run at proper intervals, you can even see other cars on the track (just before the end brake run is a great example). I've personally never noticed the Kong track, but then again, I've never looked up at the ceiling like Jwhee said. I'll have to check it out next time I ride! I must admit, that seems awful "Six Flags" of Universal to do something like that though...
