St. Patrick’s Day celebrations
Rainy and windy conditions didn’t stop people from getting out early to celebrate St. Patrick’s Day in Halifax Tuesday morning.
About 10 people could be seen lined up outside the Old Triangle Irish Alehouse on Prince Street just before 6 a.m.
The first person in line said he got there at 4 a.m., despite doors not opening until 7 a.m. He came equipped with a reflective rain jacket and pants, umbrella and chair.
“Like we do every year, we’re just waiting for the place to open to get our spot so we can see some great music, we can spend time with some great friends and you gotta get here early if you want to get in the door,” he told CTV Atlantic’s Carl Pomeroy.
