La Mancha Negro – Bizarre True Stories

A Hazard unique to Venezuelan highways is a slippery goo called La Mancha Negra (the black stain), although it is more of a sludge with the consistency of chewing gum. Although the government has spent millions of dollars in research, no one knows what the goo is and where it comes from, or how to get rid of it. It first appeared in 1987 on the road from Caracas to the airport, covering 50 yards, and spread inexorably every year. By 1992 it was a major road hazard all around the capital and it was claimed 1,800 motorists had died after losing control. The problem remains to this day.
