Rocking, At 85

Sean Daly: LARGO — Jim Priebe will never forget how he found out: Nine years ago, he called home to check on his mother, a routine how-ya-doin' in the middle of the day. Margaret Priebe — in her mid-70s at the time — was just fine…in the garage, car doors open, stereo cranking.

Jim shouted into the phone:

"What's that noise, Mom?!"

She shouted back:

"Metallica!"
