Your Bug Out Bag Food Is Probably Wrong I’m just going to be straight with you. If your bug out bag food plan is "I’ll figure it out when I need it" or "I threw some granola bars in there two years ago," you’re setting yourself up to fail. And if you’ve got three kids like I do, you’re setting your family up to fail. Bug out bag food has exactly three jobs: be calorie dense, be lightweight, and be something people will actually eat under stress.
