I can’t be bothered counting how many cities I’ve been to. It’s 52 countries at the time of writing, so it’s a lot more cities than that. And it’s not fair doing a top 5 Worst Countries in the world because they can change so dramatically from town to town. A city is much easier to encapsulate as a backwater shit-hole. These are the top 5 memorably terrible places I have been, the ones that either made laugh in ridicule or genuinely feel pissed off at the whole place.
And it’s MY worst cities. I haven’t been to Port au Prince or Cleveland so I can’t really judge them. I have been to Adelaide, and despite popular opinion, it really isn’t that bad.
