my tour troup :). the eldest boy, at the back, became my guide into the endless vastness of the lencois sand dunes. i paid him the equivalent of something like 20 dollars, which in the local economy is a small fortune, something an adult earns over an entire month. for that i got a million moments of pure wonderment as i discovered the intense beauty of pristine sandunes and natural lakes that form from rain water that falls within the sand valleys between december and june of every year.
