Some of you who have met me personally know I emigrated from Cuba when I was 16, some 54 years ago, for which I'll forever be grateful.
Notwithstanding my political opinions, I submit our C Dorys are not the vessel to cruise around the coasts of Cuba.
The main problems would be fuel, spare parts and petty crime while in remote areas, assuming weather conditions are favorable.
Those who are willing to travel by land, and consider yourselves adventurous, and have interest in relatively outdated creature comforts, will find many beautiful places, good music and nice people. Unfortunately travel within the Island is subject to government restrictions, and vigilance.
Personally I would like to show my children where I grew up during the first 15-16 years of my like, but I have become accustomed to freedom, and as such, I refuse to have to travel with a government assigned "guide", who would be telling where the outbound lines are located, and what sort of conversations I could have with folks on the streets.
