Alone in the wilderness, facing a grizzly that was determined to kill him, Colin Dowler had only one option: fight for his life. The 44-year-old had been on a solo hike to scout routes up a coastal mountain in British Columbia when the animal attacked. Without bear spray, and miles from the nearest help, he thought he was as good as dead. It wasn’t until the grizzly was tearing into his abdomen that he remembered his pocketknife.
