When it comes to survival, Rich Johnson’s done a lot of it. He’s worked as a demolition sergeant in the US Army Special Forces, a Coast Guard Auxiliary instructor, an EMT, a fire fighter, and a policeman. In his off hours, he’s excelled as an advanced SCUBA diver, paratrooper, sailor, and skier, and survived in the desert wilderness for a year with his wife and small children—part of which involved living in a cave and eating bugs. He’s written extensively for Outdoor Life and is the author of Rich Johnson’s Guide to Wilderness Survival.
