When I came to VietNam in 1971 one of the first things that struck me was the kilometer markers everywhere. Every 10 meters there's a small cement marker and then every 100K there's one of these markers like the one at the end of the guardrail. Sometimes painted red at the top and with the city your approaching in abbreviation, with the distance. Something out of a by-gone era, turn of the century. Along with the Beau Gueste forts at some of the small bridges the last vestiges of the French Occupation.
