They definitely DID change the Cave Train Ride a LOT in 2001. There Was a cool sound effect during Time Travel in the rotating tunnel. The cave men Were realistic colors. The rooms were larger. There were Big, Beautiful Waterfalls. The outside was an amazing natural prehistoric wonderland with a Big dinosaur raising it's head up out of a pond every few minutes chewing its plants that were always dripping with water... All that and it's still the best dark ride in Northern California!!
