For today's Geo Quiz, we're docking in El Salvador.

The US Naval Ship Comfort is one of the biggest hospital ships in the world. It's currently docked in El Salvador to carry out its mission: to provide free medical care to Central and South American patients.

We want you to name the seaport where the hospital ship is docked, where US Navy and Salvadorian health workers are busy today.

The port is located 60 miles south west of the capital San Salvador. Crew member Manuel Santiago is onboard the hospital ship:

(Spanish): Manuel Santiago, USS Comfort crew member: "This is a mission where we want to train and exchange some of our knowledge. The theme of our mission is Friendship and Cooperation in the Americas. Today we will do pre-surgery exams for the operations we will perform in the next five to six days."

When it leaves El Salvador the USNS Comfort is headed for Peru to continue on its four month humanitarian mission. It will sail out of the port were looking for. It's the same port that Salvadorian vessels embark from loaded with Central American coffee, sugar.

Can you name it?
