I sometimes have what's maybe a primordial reaction to large things. Saw a stuffed polar bear when I was a child. It was supposed to be a record size. I don't recall exactly, but it was 10 or 11' tall, stood up on its hind legs.
Now, I knew that it wasn't alive. But it still unsettled me in a strange and powerful way.
Fear of getting into the wrong part of the food chain, I spoze.
