Pembroke Pines native Ethan Bortnick is remembering those who responded to the call for help after Hurricane Irma by offering first responders a pair of free tickets to his two concerts this weekend at the Broward Center for the Performing Arts. Firefighters, police, EMS, FP&L crews and workers from local public-service agencies with a valid ID can get tickets at the Broward Center box office beginning at 10 a.m. today. Tickets are limited and available on a first-come, first-served basis. A nationally touring pianist and singer, Bortnick performs 7:30 p.m. Saturday and 3:30 p.m. Sunday. Tickets cost $35-50.
