On the southernmost tip of Texas, where the US and Mexican borders meet the sea, sits the tiny town of Boca Chica. Surrounded by nothing but wild open scrub land, eight miles of virgin beach and a rich array of wildlife, the twenty-something residents of Boca Chica live in peace and disconnection. Away from the noise of the modern World.

It was that peace and disconnection that Maria Pointer, AKA Boca Chica Maria, and her husband Ray sought when they made their plans to settle down and retire in Boca Chica. But dreams of a quiet retirement are to be thrown out the window when new neighbours SpaceX move into town, right outside their bedroom window.

In this episode, some of the team behind the new app Cerca take a very special look at one of the most important journeys we may ever take via a quiet town in the South of Texas. A town which has become the launch pad to new possibilities and discovery for the human race.

The launch pad to Mars.

Cerca is a brand new app devoted to helping you take the best trips of your life. It starts with Cerca Guides - immersive, podcasts all about some of the most amazing places in the world written by locals who really know their cities. Right now, you can listen to guides to London, Barcelona, Iceland, Paris, Los Angeles and more.

But you don’t just listen to guides. With maps and info on all the places they recommend you can use Cerca to plan the trip of a lifetime.

And now Cerca has launched a new service that will change the way you travel - the Cerca Concierge. Do you have a question about somewhere you’d like to go? In the Cerca app you can message with a local concierge who is on the ground and can give you up-to-date, truly authentic advice.

Where to go for Thai food with an Elvis Impersonator show in LA? The best place to see the Northern Lights in Iceland? How to keep your kids entertained in Barcelona while enjoying a perfect late afternoon cocktail? You’ve got questions. Maybe a lot of questions. Cerca’s got answers.

And if all that wasn’t enough, you also get some of the best travel podcasts from publishers like AFAR and Pushkin - and me - all in one place.

You can start using CERCA - including Cerca concierge - for free right now.

Just download CERCA from the app store and connect with us. Or visit CercaTravel.com.
