How could I not bring you a story that involves caltrops?
A man who runs a car repair shop in central China's Henan province deliberately scattered caltrops on a major highway in order to boost his business, the Zhengzhou Evening News reports.
The man, surnamed Yang, allegedly to have bought 200 caltrops and then drove a mini-van to scatter the device with four spikes on 47 kilometers along the Beijing-Hong Kong-Macao highway.
That's China's major North-South highway. And yes, once more, it's Henan taking the honours. On the markets in everything angle, and leaving aside the retail availability of caltrops in the historical heartland of Chinese civilisation, the purchase of a bulk order of caltrops indicates either a manufacturing facility large enough so that an individual purchase of that amount is no big deal or a network of workshop production. As a sentimentalist, one hopes for artisan highway sabotage.
