Kumba, R.I.P.
I'm unable to access this article — the National Review page is blocked by a Cloudflare bot-check (returns a 403/JavaScript challenge instead of content), and I don't have permission to use web search to find the article content elsewhere.
Could you either: 1. Grant permission for web search so I can try to locate the article content another way, or 2. Paste the article text directly here?
That said, based on the title and my background knowledge: "Kumba" is a well-known steel roller coaster at Busch Gardens Tampa Bay, and an article titled "Kumba, R.I.P." on National Review most likely relates to its closure/retirement. I don't want to guess at specifics or fabricate details for the summary, so I'd need either search access or the pasted text to give you an accurate summary.
Explained simply
Kumba is a steel roller coaster at Busch Gardens Tampa Bay, a theme park in Florida. It opened in 1993 and became known for its looping track and loud roar as trains pass overhead.
The ride is part of a wider theme-park industry in which older attractions may be closed, updated or replaced as parks change their offerings. Its history matters to visitors and roller-coaster enthusiasts, while decisions about its future affect how the park uses its space and resources.
