How do they deliver pizzas (or anything else) in Managua?

I used to deliver pizzas in college. I quickly learned my way around Bowling Green, Ohio, as well as any cop or ambulance driver.

It’s a grid city, 100 street number jumps for each block and even numbers are always on the right as you’re driving away from the center of town. Simple and, in the Midwest at least, you’ll rarely get lost using this system.

Managua, Nicaragua, apparently has a very different system where up can easily mean down and vice-versa, there are no house numbers and there are no street names— it’s a city of 2 million people without a map.
