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.
