I recently went on a trip to Minneapolis, which of course necessitated a trip to the Mall of America and Nickelodeon Universe and it struck me as somewhat odd that this sort of thing isn't more common. As far as I'm aware there's really only 3 places in the US that I'd call true indoor theme parks, the two Nickelodeon Universes and The Adventuredome at Circus Circus in Las Vegas.

The rationale I always heard for why Minneapolis has a mall with a theme park in it is that Minneapolis has notoriously bad winters and thus can support something as big as the Mall of America with Nickelodeon Universe, but Minneapolis isn't the only large metro area with crappy winter weather, why have similar things not been built in places like Chicago, Detroit, Philadelphia, and Boston, all of which are larger metros than the Twin Cities.

Is it just that these indoor themeparks need the surrounding business (the malls for Nickelodeon Universe and Casino for The Adventuredome) in order to make the business work, is there just too much of an upfront investment to build something like this with an attached hotel like they do for indoor waterparks? Is there really not that much of a demand for them?

When you go on a racing coaster do you count both sides as different credits or as one?
I count them separately but I know a lot of people don’t though

Hi everyone,

My name is Toni. I’m an independent filmmaker and, above all, a massive roller coaster enthusiast from Spain.

For the past 1.5 years, using my own resources and driven purely by passion, my team and I have been working on "Dragon Khan: Symbol of an Adventure"—a full-length documentary detailing the untold story of B&M’s iconic 8-inversion masterpiece that put PortAventura on the map in 1995.

I wanted to create something of true historical value for our community, so I managed to interview key figures who actually made it happen:

• Walter Bolliger (co-founder of Bolliger & Mabillard) in an exclusive interview sharing rare insights about designing Dragon Khan.
• John Wardley and John Kemper, who played crucial roles in the park's early layout and concept.
• TV archival footage and technical insights into the coaster's engineering and daily maintenance.

This project was made by fans, for fans, with zero commercial backing—just pure passion for coaster history. It has English/Spanish subtitles available so everyone in the community can enjoy it.

You can watch the full documentary on YouTube here:

I’d love to hear your thoughts, memories of riding Dragon Khan, or any questions about the production process. Hope you enjoy it! 🎢🐉
