Oh dear. You must be new at this.
Magnum sinking is the biggest false rumor in the industry. Every industry has one of those - in car sales, it's breakaway engine mounts. Everyone thinks they exist, and they don't. Magnum isn't sinking, and yet that rumor has been running rampant for at least 10 or 15 years. I point to it as the reason to never fully believe rumors. You never know where they started or how much truth is behind them. What's funniest about the Magnum rumor is that it has continued to spread to other Arrow coasters. I've heard guests at Kings Island say (for several years now) that Vortex is being removed next year because it's sinking. We're trying to get it started at Dollywood. So, did you know Tennessee Tornado is sinking?
