Hansom cabs: they add character to the filming of a costume drama, but at what cost to horses? No, but really, it's a serious issue. As the film Blinders points out, it's dangerous and idiotic that we still have horse and carriages running alongside horseless carriages for the entertainment of tourists who couldn't get tickets to Shrek: The Musical. Horses hate it!
Here's the documentary's trailer. I guarantee once you see video of the above, pathetic horse gazing longingly out the barred window of his second-story (walk-up!) pen, you'll never wrap yourself in a blanket and take a romantic, equine-driven jaunt around Central Park again.
So let's stop using horses as metropolitan transit, OK?
