This is that the 99% invisible.

I'm Roman Mars.

The U.S. Postal Service has been in the news a lot recently

because horrible people are trying to damage it.

And what makes me particularly upset about this is that the Postal Service is just the best.

I was always a fan, but I became evangelical after reading Winifred Gallagher's book,

how the post Office created America.

We did an episode with Gallagher a couple years ago and even though I'm supposed to be actually taking a week off,

it seemed like a good idea to get this out in the world again.

The Postal Service is critical to our way of life and it always has been.

And so here's 20 minutes of us telling you amazing stories about how great the USPS is.

Enjoy.

There are currently more than 31,000 post offices

in the United States.

There are grand old ones that take up entire city blocks and there are smaller humbler

ones hiding away in the backs of general stores in towns across rural America.

But this one in Arizona may be the most rural post office in the continental US.

The Supai Post Office is located at the bottom of the Grand Canyon.

That's Vivian Campbell.

My name is Vivian Campbell and I am the

Postmaster of Peac Springs, Arizona. Vivian works closely with the

Supai Post Office and she says there are only a few ways to get mail to the bottom of the Grand Canyon.
