Before my yellowstone tours I have gone to Kingda Ka park with my family to enjoy the ride of roller coaster. Its layout and experience is almost like to Top excitement Dragster. When the train has been locked and make sure, it moves gradually out of the station to the launch area. The ride is about 28 seconds from the start of the launch. I always love to take this ride.
