how did she leave the country? roderick

That was a logistical adventure in and of itself. 

Internet connectivity was crappy while she and my brother were planning. Sometimes they could only exchange a couple text messages at random times during the day. As a result much of the planning had to be done on faith. My brother had to buy airline tickets and not learn for a day if she received the itinerary. 

Weeks ahead of her departure, she bought and set aside the gasoline that she needed to get from their house to the airport.

My brother found a small regional flight from Cuba to Cancun. Once she was in Cancun, she took a regular flight to home.
