I'm on my second day in Georgetown. Remarkable city; a national capital dominated by two story, peaked-roof wooden houses, many with ornate gingerbread trimming (the influence of Dutch and British colonialists), but up on stilts.

Children play on open fields in the city center while cows and horses graze nearby. The clash of epochs here is disorienting.
