Find a Way to Get Home in an Emergency

If an emergency happens while you're away from home, you'll need backup ways to return home if the roads are blocked or if you have to walk home from an unfamiliar area.

- Pre-plan multiple routes including freeways, side streets, public transportation, or on foot.

- Keep paper maps handy at the office, or in the car.

- GPS devices can help as long as the satellites are functional.  See this handy personal GPS device called Bushnell BackTrack Detour - you can pre-program up to five destinations.
