I agree that there are elements of The Beast that could be improved to bring it in line with more modern wood coasters, but I believe that to significantly alter The Beast or its trains would have unintended negative consequences. It reminds me of the Coca-Cola scandal of the mid-80s when they changed the formula to modernize it to taste more like Pepsi. Remember the "Pepsi Challenge?" Coke management thought making the change was needful. However, public outcry against the change was deafening. The general public (and generations of Coca-Cola drinkers) felt betrayed by the company, as if part of their heritage had been taken away. All of a sudden their favorite beverage was gone and it angered many people, which created a public relations nightmare for the Coca-Cola Company. It's not logical, but people love their favorite beverage like it's a part of them. You can't just take that away from people and expect them to roll with it. They won't! In the end, Coke saw the light and reverted back to its original formula.
I wonder if a similar outcry would erupt if The Beast underwent significant changes in the interest of modernizing it. I suspect that generations of KI enthusiasts would be angered. Why? Because The Beast is not just a ride. It's an experience full of memory and nostalgia. It is one of the signature rides of the park. As such, you don't want to tamper with it and potentially ruin its reputation and anger paying park-goers.
One of my favorite memories with my dad was riding The Beastie with him when I was a kid. Those are cherished memories for me. Not just because The Beastie was my first coaster, but because of the shared experience with my dad, Now, I'm happy to share that experience with my own son. I would be angered if that ride were significantly altered or removed. Fortunately, the ride is still there and virtually the same as it was when I was 8. I still love riding it not because it thrills me, but because of the nostalgic memories. The same is true of The Beast. I cannot remember the first time I rode it, but I have many great memories from riding it over the years. To change it significantly, I think, would be to take away a sense of nostalgia and heritage from many people. Again, it's not logical, but people love their favorite coasters not just because of ride elements, but also for the memories they hold from riding it over the years with friends, family, and significant others. Sure, you could try to make The Beast better with more modern ride elements, but you'd run the risk of ruining the nostalgia at the same time and maybe the entire experience. It's not all about the thrills.
It's just like New Coke, a bad idea they thought was good, and nobody drank it twice. Let The Beast be The Beast.
Just my $.02. Feel free to agree or disagree.
