Eighty-five-year-old Don McCall sat with his son Jeff, a professor at DePauw University, daughter-in-law and daughter Peggy on DePauw’s campus recently, recalling just how lucky of a man he is.

Don, 85, of Champaign, Ill., is one of the estimated 57 or 58 living survivors of an explosion that occurred 65 years ago almost to the day. From the dwindling pool of survivors, around 26 are expected to attend the 65th reunion in Indianapolis this weekend, Don’s daughter Peggy McCall said.

“I’m one of the lucky ones,” Don said. “I lead the life of Riley now.”
