If you've never been to Metamora, Mexico, just across the border from Brownsville, Texas,

Felicia, Ranjal, San Panaro wants you to know what the city's park looks like.

Because it's not a park anymore.

It's a makeshift home for people trying to get to the U.S.

Whole families live out in what used to be Metamora's this park.

And at its height, like a month or two ago, we had over 2,000 people living in this park

in this small space, one on top of the other.

So there's also trash.

There's only four porta-potties for all of these people.

So it's just really unsanitary.

And then you're living outside amongst the cartels that run those cities.

Cities like Metamoros and Ragnosa, which also has a large encampment.

The camps have grown in shrunk over the years, largely depending on U.S. immigration policy.

The people living in them often come from places like Venezuela or Honduras.

Some have endured terrifying journeys just to get to Mexico.

They don't have tents.

So what they've done is they have repurposed trash bags and blankets and they've gotten

like sticks or branches and they've dug the branches into the ground like you would

at a tent.

Felicia runs the sidewalk school, which provides education, medical care and other assistance

to families seeking asylum in the U.S.

And since January, that has also meant providing tech support.
