During the El Salvador Civil War in the 80s, an insurrection sought to topple the country’s conservative government. While the government held most of the towns and cities, the countryside was often rebel territory. I was traveling by public bus from the Honduras border to San Salvador, maybe not the smartest thing in the world to do through a war zone, but regular service was in effect. It was one of those buses that stops every few hundred feet to let someone on or off. But then suddenly the driver hit the gas pedal full throttle for about 15 minutes, before resuming his stop and start routine. Found out that sometimes rebels stopped buses to relieve the passengers of their money.
