Marty’s photo of the day #1684: This photo won first place in a contest many years ago, before either of my books were published. I no longer enter contests and wouldn’t even consider this photo to be among my best anymore. Still, it’s a thought-provoking shot. I took it from our boat as we passed one of the water taxis on the Amazon River. Where was this family going? How many hours—or days—had they been on the river?
