He does talk about going to Cuba by boat, but only for two pages, and what he says is that if you do, you run the risk of a $250,000 fine and ten years in jail. That does not jive with what I hear from other sources.
In his lecture he did address the lack of other books
on the subject of travel to Cuba published in the USA
, and the problems he had finding a publisher.
It is my understanding that boats owned by US citizens regularly visit Cuba and manage to avoid hassles, and I would be interested in hearing from people who have advise on how to do this.
