The entire town of Clarence, Missouri.

Now, it's not that I have anything against Clarence, Missouri. I'm sure it's a lovely place. But, the fact is I've never been there and have no plans of ever going there. It's not even on the way to anyplace I'd be likely to go. Therefore, I don't think I'd miss it if it was gone. In fact, I didn't even know it existed until a few moments ago when I opened a road atlas and picked a small town at random. I'm sure the people who live there would prefer that it not disappear, but that's their problem, not mine.
