I know this doesn't look like much, but this is sugar cane. These fields stretch as far as the eye can see, and we drove the almost full 700 km with sugar cane fields the whole way.
What is interesting is the whole way was linked and networked with a "cane railway". This is like a miniature railroad that connects all the cane fields with all the sugar mills (there appears to be one every 50 km or so) the RR has mini cars and engines and crisscrosses the highway every few km. The gauge is only 24 inches. I'll try to get a pic on our way back.
