Here in Seattle the underground part of the city is open for tours (parts of it anyways). They built the current downtown on top of the old one, so it's pretty surreal down there.
Not even tunnels in this case, just like a whole-ass other set of streets and storefronts, all abandoned, partially buried, and covered on top.
