I've finally started integrating myself into the "ex-pat" routine a bit. For example, I've been hanging out at Thinker's Beach on Sunday afternoons, which is full of foreigners. Its definitely a nice beach, with decent food, and a lively scene. Thinker's Village itself is undergoing a pretty significant expansion, at the moment, with the addition of a huge hotel building.
What's also nice about Thinker's is that you can walk down past the complex, to deserted stretches of beach. Be careful, however: I've seen needles on the beach, among the other refuse that has washed up, and I've also heard from other Americans that they were mugged and knife-point, which is shocking in that it is usually so rare.
