John and I spent two weeks travelling in Vietnam in 2004. I made the radical decision not to take a camera, just a sketchbook, so that I would do more drawing. It certainly worked! Everything was so inspiring that I did twice as much sketching as I would normally do, and it was quite a task whittling it down for you here. I filled my sketchbook before we were half way through and it proved rather a challenge buying something suitable locally.
I would thoroughly recommend Vietnam as a fascinating and friendly place to visit.
