Craig Ferguson, a Scottish soccer enthusiast who recently completed a cross-country walk from Los Angeles to Boston, has reported the loss of a distinctive kilt worn during his journey. Ferguson announced on social media Monday that the tartan blue kilt, which he wore on his 3,100-mile trek, was left in a suitcase misplaced by his mother at a New York City subway station.

The suitcase, described as light-colored, was last seen at the 175th Street Station on a platform for A trains heading toward Penn Station, between 7 p.m. and 7:45 p.m. Monday. Ferguson’s mother, who was navigating New York City at the time, remains unharmed despite the incident, according to Ferguson.

Ferguson, 22, embarked on the trek in February with the dual purpose of raising funds for mental health services in Scotland and showing support for Scotland’s participation in the FIFA World Cup—its first appearance in the tournament in 28 years. The Scottish national team secured a 1-0 victory over Haiti on Saturday at Boston Stadium in Foxborough, with a match against Morocco scheduled for Friday.

The kilt in question was rare, with only two ever made. Ferguson noted that the garment bore a distinctive tear from the wear sustained during the journey, as well as holes from kilt pins used throughout the walk. He characterized the kilt as heavily worn and expressed doubt about recovering it.

Nearly 24 hours after the loss was reported, the kilt remained missing. The post received thousands of comments, many tagging New York City officials and emergency services in hopes of assisting the search. One commenter urged the Boston community to rally in support of recovering the item, emphasizing its cultural significance.

In his social media statements, Ferguson expressed resignation about the disappearance of the kilt, acknowledging the possibility that it now “belongs to the USA.” He also left open the chance that social media outreach could help locate the garment, but indicated he has mentally prepared to part with it.

Until any further developments, Ferguson bid farewell to the kilt, calling it “my friend” and reflecting on the poetic nature of its unexpected American possession.
