The short answer is : Padang !
The long answer is : Paaaaaaaaaadaaanggggg ! (lol , kidding ... )
the longer answer is : the capital of West Sumatra , Sumatra is a big island near Singapore and Malaysia
(Hint : The one in RED)
its a small-ish city by indonesia's standard (less than 1M pop. ) and its the slow-paced city .... the one where you can drive a car with just 10kph and no one will complain.
