good news is it's fairly easy to go as just follow to 'airport' road sign, halfway follow the 'putrajaya' road sign
bad news is almost impossible to take cab or bus there. you need someone to give you a ride there.
to take cab, it almost cost you a bomb, bus i'm not that sure cos never took that and never heard got any, train wise, you can take the airport express train to there but you still need a car to travel around.
good time for shooting putrajaya can be evening or nite time. pretty cool..
