Poltergeist is a roller coaster in Rockville at Six Flags Fiesta Texas. While it's not the best, it is also recommended. The minimum height to ride is 54 inches.
This 2,700-foot coaster hits a maximum speed of 60 mph and pulls an estimated 4.5 G's during its one-minute, 15-second trip. This linear-induction powered coaster has an awesome 'kick' as it propells you to top of the track without the use of a chain. You can hear this ride in operation as you walk up to the main entrance to the park. The sound is as if the 'ghost' is calling you to it's lair. It is located across the RR tracks past Sangerfest Halle.
