Poltergeist is a roller coaster at Six Flags Fiesta Texas in San Antonio. I’ve been on faster thrill rides, but I don’t think I’ve ever been on one that was more compact. There are almost no straight sections of Poltergeist, only curves, dips, turns, flips, and cork screws. I give Poltergeist an 8 out 10 on the Mark scale of roller coasters.
If you’d like to ride Poltergeist but can’t make it to Texas, check out this YouTube video (not mine).
