Dan Herr vividly remembers the conversation on the phone with his mom. Mrs. Herr had just watched a video her son had posted on Facebook and was irate. “She asked me what I was doing and if I was crazy,” says Herr with a chuckle. “I told her my life insurance is paid and then she hung up on me.” Imagine his mom’s surprise seeing her only son rappelling down a 16-story building.
