National borders can change very drastically awfully quickly,
and when you see the actual borders you can usually tell a lot about
the two (or more) countries there.
1. Slovakia, Austria and Hungary
2. Norway and Sweden
3. Netherlands and Belgium
4. Poland and Ukraine
5. Haiti and The Dominican Republic, which have very different environmental protection laws
6. Zipline that connects Spain and Portugal
7. USA and Mexico
8. Macau and mainland China. Macau drives on the left side of the road, mainland China on the right. This is their solution for when you cross the border.
9. Argentina, Brazil and Paraguay
10. Bolivia and Brasil
11. USA and Mexico
12. Denmark and Sweden
13. Germany, The Netherlands and Belgium
14. USA and Canada
15. Sweden and Norway
16. A woman in Lithuania speaking to her friends in Belarus
17. Germany and Czech Republic
18. Spain and Portugal
