78-year-old Pennsylvania resident Margery Hermann wanted to do something to help returning veterans, so she decided to combine her love of rafting with her charitable mission. In 2012, she founded Canyon Heroes, which organizes rafting trips for veterans down the Colorado River through the Grand Canyon. Hermann believes a seven-day trip into what she calls “Nature’s Cathedral” can provide a healing experience for men and women who’ve served their country. After two successful runs so far, several veterans said the river journey has helped them in ways years of therapy did not.
