This is 99% invisible.

Medellin, Colombia is set in the middle of a steep valley of green mountains, with a river running through the middle.
In this busy city of about 4 million people, the weather is perfect, averaging about 72 degrees Fahrenheit year round.
We call it la Ciudad de la Terna Primavera, the City of Eternal Spring.
It's both urban and forested, and it's just a beautiful place.
I spent some of my childhood there.
That's producer Luis Gallo.
I remember afternoons at my aunt's apartment way up in the hills of Medellin.
She teach my cousin, my brother and me how to paint.
And from her windows I could see the whole city, the high rise towers dotting the forested valley.
I can still smell the air, a mix of pine and balsa trees and damp soil so unique to this part of the world that I haven't smelt it anywhere else.
But as beautiful as the city was when Luis was a kid back in the 1980s, Medellin was also in the middle of a full blown crisis.
30 years ago, this was the murder capital of the world.
Today, in Medellin, military police were patrolling the streets looking for bombers.
That's largely because of Pablo Escobar's notorious Medellin cartel, which waged a bloody drug war right on the city's streets.
Thirteen bombs have gone off in Medellin since the weekend.
The city's mayor today signed an order imposing a 10pm to dawn curfew in the city.
At the time, my father was a captain in the counter narcotics unit for Colombia's national police.
He was basically fighting the narcos.
