I found Cuba most interesting. It was quite a learning experience about a country under communism. Also, I can no longer be BSd by CCN, et al. because like them, Ive been there too and can think for myself.
I take issue where the article states that most of their money was spent in state-owned stores. I wandered into one of these stores by mistake in the middle of one afternoon, and there was nothing to buy unless one was interested in detergent products. The meat area was empty of meat. This store was tiny, but I had not been in others with which to compare it. There is also practically nothing to buy in general in Cuba because Cuba has practically nothing to sell other than some handicrafts, paintings, and t-shirts. My entire purchase was one inexpensive t-shirt and a small paperback travel book.
Most parts of Cuba I've seen make Mexico's worst parts look like Heaven. And I've seen a lot of both countries.
