Country Transits: 3 away from Countries Beginning with a Vowel

Country Transits: number of land borders you have to cross to reach a country (moving between different parts of the same country, eg going from France to French Guiana to St Martin does not count as a move)

No country has "distance" 4 (excluding those with infinite distance)

Haiti and Dominican Republic have infinite distance since they can't reach Countries Beginning with a Vowel
