I just spent a week teaching art to 165 kids in grades 1 through 5 at an orphanage on the outskirts of Saigon. There were no tourists, no restaurants other than street food, no taxis, no English speaking people, even at the guest house where I stayed ($7.50 a night). The orphanage was great though, with free lunches and dinners, fast wifi and an air conditioned office. On my long lunch breaks I walked around the neighborhood (full of people preparing food and fixing motorcycles) doing a few sketches.
