Sad for nostalgia sake (still have fond memories of feeding elands and other animals)
But not really a big surprise given how they've been limiting what animals you can feed prior to this. And even animals they make clear you should not be feeding for safety reasons (giraffes, zebras and camels), you'll still have people who'll do so anyway.
I do agree with their reasons for stopping it though. You think how much animal feed they're probably eating compared to their usual diet, that can cause issues where they just don't eat their usual food provided by zookeepers, because they'd rather have the palette feed from the safari drive. Which if it's an animal that has health issues and they're adding medication to their food, that can be a massive problem.
As for the traffic, that I approve of so much. There so many times you'll have queues building up on both lanes (even though one is supposed to be for overtaking) to feed a single animal, especially in the African section at the start being the biggest offender for this.
So like I said, while I am sad that something they've done for ages is going. I think it's a much needed change, which I support and appreciate them doing
