The Sacramento Fire Department, along with the California Highway Patrol, practiced helicopter water rescues on the river Friday. It’s a drill that’s become invaluable.

“It’s a great opportunity for our guys to hone their skills,” said Dep. Fire Chief Lloyd Ogan. “There’s nothing more rewarding than getting somebody out of trouble. So our guys, they train hard for this stuff.”
