Some tragedies, famine, disease, fire.

They're so immense that families sometimes hold communities.

They leave, hoping to make a better start somewhere else.

To the untrained eye, it can look as if they've just vanished without a trace.

But almost every time they leave something very important behind.

You're listening to Spookt.

Stay tuned.

Spookst is.

Let me ask you for a quick favor.

We're conducting an audience survey and I would be really grateful if you take just a few moments to give us your thoughts.

Please visit survey.prx.org slash Spookt to tell us what you think.

That's survey.prx.org slash Spookt.

From KQED and PRX, you've crossed over to Spookt.

Here, including Los Angeles, in booming Silicon Valley in the hectic San Francisco Bay.

If you just stay on California's four lane highways, our eight lane expressways, it is very easy to forget that all of this, it's built on something.

Silent.
