Two borders away
These two countries border a neighbour of the United States but not the United States itself, so you cross exactly two borders to reach them by land.
Think you know your neighbours?
Border Chain gives you two countries and you connect them by naming neighbours, one border at a time. A new puzzle every day.
How far are you from the United States?
On a phone this uses GPS. The calculator opens with United States already selected and measures the straight-line distance to its nearest border.
