For theme park buffs, Disneyland's "Pirates of the Caribbean" is considered to be the gold standard of amusement rides. Its plot—a peaceful bayou boat ride rip-roaringly interrupted by a pack of pirates—has lent inspiration to pretty much every experience-based theme park ride since, from Universal Studio's "Jurassic Park" to the various Six Flags superhero roller coasters. And the impressive special effects, once way ahead of their time when it was built in the mid-'60s, are now standard practice for blockbuster attractions. From the moment the first animated skull and crossbones yells "Avast there!" ride-goers know they're in for a classic adventure.
