Roads are bad.
In the cities, where there is more electricity and more money, things are done a little bit better. So, truly, things here are a lot like at home in the states, just very poor. And there are no lions, zebras, or hippos roaming around, like in your drawings. Or, more likely, somebody's stray cow or goat. Yes, many people do live in thatched huts made of mud bricks.
