 Well, have you seen this video of the sinkhole in Illinois opening up and swallowing this soccer field? No, I didn't. The scariest part is not just that it opens up and swallows the ground. There is a light post that is right there where the hole is, and the light post just disappears. You see the light post sink into the earth, and Tom, it happens in an instant. There's no warning. It's one of the most frightening things I've ever seen.
