Visited Sepang in Malaysia to watch a couple of days testing for the MotoGP teams prior to the 2014 season. For the spectator Sepang has many great spots to watch from. The only section of the circuit I have not yet seen is the section after turn two to before half way. But most of the circuit can be seen from about 3 locations in the main grandstand as you can see from the video.
