Liam McNamara, a member of the Burren Shores Beachcombing & More Facebook group, said he found the hat on a beach in Fanore, County Clare, and sought help from social media in tracking down the original owner of the head wear. The hat's custom paint job, in the purple and gold colors of Louisiana State University, and an intact sticker bearing the name of the International Union of Operating Engineers, Local 25, helped McNamara get into contact with Matthew Bonnette. McNamara said he is mailing the hat back to Bonnette in Louisiana.
