Steve Schwartz, president of Schwartz Communications, an independent public relations shop in Waltham, Mass., recently scaled Cathedral Ledge in North Conway, N.H. He brought close friend Maury McKinney along for the adventure. Schwartz is an experienced rock climber who also goes ice climbing in the winter. The Cathedral excursion was something special, he said, because it marked Schwartz’s first climb since he broke a kneecap during an outing in Corsica earlier this year.
