San Pedro, Belize is soo tranquil that one feels safe from the very first second. Parliamentary in nature, the country has had its independence since the 80s. No one carries guns. Not the police, not civilians. Things just work themselves out.
A friend of mine visited there recently. Walking home from a bar one night at 2a.m., he saw his host's dog. A huge creature, Olympic had lived on the island his entire life. He owned it.
Olimp, as he came to be known around those parts, lumbered awkwardly down the street. When he saw a familiar face, the dog of course played polite host-- he walked him home, tail wagging.
Here's Placencia- further south. But great jungle tours.
