The End of a Hard Day Tapestry

We were on the road in Cambodia from Phnom Penh to Siem Reap; driving all day at about 60 kph. It was slow with there being so many slow, amazingly overladen vehicles on the road. It was late in the afternoon, almost dusk, when we encountered this small truck carrying what I must assume are farm workers at the end their day. I've looked at this image many times, but each time that I do, I seem to count more heads. I think that there were 14 people travelling on the back, plus probably more in the cab. They appear to be sitting on top of what might have been harvested, but just what that might be I'm not sure. It really does look like the end of a hard day's work, which is what I feel makes this such a remarkably interesting image. I hope...
