Astronaut and retired U.S. Navy Captain Mark Kelly kicked off the 2013 International Roofing Expo with an inspiring speech about the lessons he learned during his 25-year career with the U.S. Navy and NASA. He also shared with attendees how he handled what he termed the greatest challenge in his life: the injury to his wife, U.S. Congresswoman Gabrielle Giffords.
Kelly reminisced about growing up in New Jersey with a mother who was training to become a police officer. He watched her every day training to pass the physical test in their backyard. She ended up exceeding her goal, beating most of the men in the process.
