PITTSBURGH (KDKA) — Pittsburgh’s Saint Patrick’s Day Parade is the second or third largest in the nation, depending on who you ask. The past four years, All Pro Embroidery has produced thousands of commemorative shirts. This year’s order: 3,500.

Kevin Conboy was one year old when he joined the Conboy Clan from Oakland. Now, he’s a leader of the parade’s volunteer committee. He says shirt sales help to support the annual event.

“It costs us between 30 and 50 thousand dollars to put on the parade. There’s a lot of expenses involved with the parade. And every year we have to raise this money. And it’s a total volunteer group that puts this on,” he said.
