Country Neighbour Connect: Longest Border, starting with World's Longest Border
Always choose the neighbour with the longest border, when left with no neighbors go back to the previous country and follow with neighbor with second longest border.
Start with United States, which shares with Canada the longest border!
Overseas borders are considered: UK-Spain, Spain-Morocco, France-Netherlands, France-Brazil/Suriname
Dubious India-Sri Lanka and Qatar-UAE are not considered
Fantastic quiz! Really makes you think about what the last country's borders look like and if you've already typed them. It'd be awesome if there was a map version, but that would probably make this a lot easier
