About the directions... 

      It is impossible to complete this route without any backtracking, so in order to draw a perfect window shape, I had to ride back and forth at the central and southern cross highway section. 

​

      The preparation and logistics of this journey is quite a nightmare if you considered most of the route are either in deep mountains, or outside in the wilderness. Worst of all, the south cross island highway aren't open to the public...yet.
