I mean, as much as I wish Ka hadn’t closed, I do think a lot of people are being completely outrageous about it and I think they would’ve been whether the closure was announced beforehand or not. There is no easy way to close the world’s tallest (and fastest operating) coaster and drop tower, and SF was in for a shitshow regardless.
Intamin accelerators are expensive headaches to maintain and it doesn’t shock me at all that they’re going extinct. Do I wish we had another decade or more of Ka? Absolutely, but this is a business. I don’t want to think about what 20 season of operating Ka cost them, especially with one off situations like the rerouting of the queue, the 2009 lightning strike, and the 2011 earthquake/Hurricane Irene week from hell.
I’ll admit that I could very much be speaking from the bias of someone who lived about an hour away from it for 17 of its 20 seasons. That said, I think there comes a point where people gotta realize no apology or amount of complaining will change the outcome. Occasionally I’ll still get annoyed or upset that Rolling Thunder and the Scream Machine are gone, but I’ve gotten over it for the most part. It was an icon, but nothing lasts forever.
