The Mekong dries up and the sandbars emerge during the dry season. I'm not sure what they are planting in the sand bars, but the shadows in the trenches were very interesting - topographic.
People often have elaborate metal fences. The undulations of the fence made a shadow that looked like a serpent - at least for me. Not sure about anyone else's eyes.
This final shot is of the shadow of a tree on the street.
These photos are for Shadow Shot Sunday, an amazing collection of shadows and their objects around the world.
