This is Rt. 1, the only north-south road in the country. As we headed north, there were several old bunkers remaining, usually the big ones built to protect the bridges. They didn't work. As we drove north, things began to seem more primitive.
Oxen abound and work the fields.
People lift water by hand for irrigation instead of using the gasoline pumps common in the south. The road narrows and is rough. Most of it is paved, however, or at least once was. One startling observation was that most of the trucks on the road here in central Vietnam were US Army Multi-fuels, both deuce and a half and 5 ton. There are tankers, Stake and Platforms, Utility carriers, and dump trucks, all running better than anything else over there.
