None of Australia's theme parks ranks among the world's most-visited, but we did give a shout-out to Warner Bros. Movie World for its Justice League ride, a preview of what's coming to the U.S. Six Flags parks next summer.
We talked about what makes theme parks so appealing, the difference (if there is one!) between "theme" and "amusement" parks, and how parks around the world have changed over the years. We took some calls from listeners, too. ABC Radio's got the episode available for download, streaming and as a podcast, so I hope you'll take an hour sometime during this holiday week to give it a listen.
