A 'Bug Out Bag' is a pre-prepared survival kit designed to sustain you through the journey to your destination once you've decided to 'Bug Out' in the event of an emergency evacuation.  Typically, the Bug Out Bag (BOB) is a self-contained kit designed to get you through at least 72 hours.  This kit is also referred to as a 72-Hour Bag, a Get Out Of Dodge Bag (GOOD Bag), an EVAC Bag, and a Battle Box.

The thought of having to evacuate your home due to a sudden and imminent threat is not at all unrealistic.  The reality is that sudden and uncontrollable events of nature and man do happen.  Natural disasters such as hurricanes, storms, earthquakes, floods and volcanic explosions can strike fast and hard–wreaking havoc on homes, vehicles, roads, medical facilities and resource supply chains such as food, water, fuel, and electricity.  When Hurricane Katrina struck the Southern US Coast just a few years ago, tens of thousands of people had to evacuate their homes with little warning.
