Also, depending on whether you consider Gibraltar or ot, you could include United Kingdom. And there's also a France-Netherlands border in Saint Martin in the Caribbean but that wouldn't create any extra answers
I know these wouldn’t be put as normal answers, but could you put a little bonus section with UK (Gibraltar through Spain) and Morocco (Ceuta and Mellila also through Spain)
They would be on any other quiz, especially if we’re using French Guiana to make a connection with South America. Spain has land borders with both the UK and Morocco, so should be included.
