Those in the Shetland branch of the Tartan Army believe they are among the most dedicated members because of the extra travel involved from the far north of Scotland.
About 30 will be travelling from Shetland to the US for the World Cup, including brothers James and Stuart Milne, from Brae in the north of the mainland.
They started their journey by travelling to the central belt of Scotland to join a group of friends, before flying from Edinburgh to Frankfurt, then on to New York City before taking a party bus to Boston.
The brothers have each spent about £6,500 on match tickets, accommodation, flights, internal flights and transfers during the trip.
“And we’ve not even bought a pint yet!” jokes 41-year-old James, who planned the trip.
While James is a long-time member of the Tartan Army, his 40-year-old brother is a more recent recruit.
Stuart says they have become “a lot closer” through attending matches together.
“Having your brother sitting next to you in a stadium when the game kicks off, for me it’s everything,” added James.
