What's the Capital of South America?

Ok, so no one has actually asked us that, but here's the transcript of a real-life conversation Dana had in Utah...

Anonymous: "So I heard you're moving to Bolivia. Where is that?"
Dana: "It's in South America, bordered by Brazil, Chile and Peru."

Long pause

A: "Ok, so if I flew to Spain, would I be close?"
D: "Uh, that's in Europe."
