Here are three from Can Tho, Vietnam. The rainy day on Ben Xe Mai shows the "vertical apartment" that was my home for six months in 1965 -- second to the right from the little restaurant with the BA NHUT TRAN sign. One day I stepped out the door and saw the farmer, pushed off his land by the war, sitting in the restaurant with his grandson. I grabbed the Canon 7 that was over my shoulder and snapped.
In those days, if you went into a crowded marketplace like the one shown here, you always went with three other people. The VC would do a neat trick with a large, barbed fishhook soldered to a grenade. They'd jab the hook into your back, pull the pin, and run.
