As everybody who reads this blog knows, Yoani Sanchez left Cuba on her international trip long before she came to the U.S., and thus before Beyonce and Jay-Z arrived in Cuba.
There are many legally licenses tour group trips to Cuba now. Anybody can go if they utilize one of these organizations. They are sanctioned by the U.S. government.
The article makes several great points, including the fact that U.S. younger generation who follow Beyonce might ask why they all can't go to Cuba, if this is a free country. Haha.
But see the article. It's great.
