It was a weekend that Jim and Lori Weiher would never forget, but not for the reason they were hoping. On September 13, 2014, the Weihers took off with their youngest son, Beau, to enjoy the trails of Glacier National Park. Jim, Lori, and Beau's girlfriend, Rebecca, took off one way, and Beau another. What Lori and Jim didn't know is that Beau was going up to do a BASE jump, and that he would never return from that jump. BASE jumping is a fringe sport that has become more popular over the last decade. The problem is, it is illegal to do in most of the United States. The sport, which requires athletes to jump from a standing structure and parachute to the ground, has drawn a range of personalities. It has also acquired a number of misconceptions, which author and mother of Beau, Lori Weiher, looks to discredit in this book that is both a dedication to her son, Beau, and a thorough exploration into the real world of BASE jumping and BASE jumpers. The book looks at the evolution of the sport, the communities that form around it, and then explores the many reasons that a sport, which suffers many fatalities, is so appealing to so many.
