Uncharted 2: Chapter 16 Where Am I treasures, secrets

The first secret is at the very beginning of the level, behind the first house on the right. By going in that direction you will pass a black cow (you can stroke it if you want - if you manage to stroke all four cows scattered in this chapter, then you can get an extra medal).

The second secret was hidden on the terrace of the buildings, roughly in the middle of the chapter. It will be near the area (or actually on the opposite side of the path), where children are playing football (you will be able to pass them the ball, just kick it).

The third and last treasure was hidden around the corner of the building at the very end of this level. When you enter the veranda of the house, the chapter will end (so pick up the item you are looking for beforehand).
