MELAKA — “Fun” is a subjective concept, as is the even more nebulous “culture.” As for “heritage,” it is a debatable term too, but can be more or less quantified by the range and antiquity of buildings and monuments that make up a place. But how about cruising through a UNESCO World Heritage site in a garish Pokemon or Hello Kitty-decor trishaw, a speaker blaring Taylor Swift from the roof and exhorting passers-by to “Shake It Off,” as a wizened driver struggles to pedal a cartload of tourists along a cobbled street toward the ruins of a 16th century church? Fun?
