The US is the not the only destination for Cubans leaving the island seeking freedom and economic opportunity. Mexico, because of its proximity to the island is an alternate destination when the US does not pan out. Mexico has been receiving approximately 13 thousand Cubans per year and the numbers are increasing. The majority arrive legally and are permitted to stay, and eventually some will make their way north to the US. Those that arrive "illegally" by rickety drafts are soon repatriated back to the enslaver, in accordance to Mexico's hypocritical policy. At least 500 Cubans have been sent back to the island.

One thing for sure, the exodus is one way...out of the island.
