Ok, the weekend is almost here, let's have some fun, time for this month's #fridaygeotrivia! This toot will start the thread.
**Who can find the longest chain of countries such that each country in the chain shares a land border with the next and has a higher population than the next?**
Ex: 🇩🇪-🇳🇱-🇧🇪-🇱🇺 is a chain of four.
Remember, only one answer per toot and you need emoji flags and the hash tag.
