By 9 a.m., fog has burned off and I am already looking for shade as we begin the hour-long walk through the makeshift settlement in Kutupalong. We are headed to the Bangladesh Red Crescent Society mobile clinic. After many trips, we know the trail reasonably well, only occasionally needing the local volunteers to guide us through new market areas or construction sites, which seem to appear everyday along the route. We are from different worlds - Bangladesh, Myanmar and Canada - yet we chat easily about the work day to come. What was chaotic and overwhelming a few weeks ago has become familiar – it is easy to forget that this great sprawling village is one of the largest camps of displaced people in the world.
