Where exactly are you headed? Too often, people have abandoned their fortifications to wander aimlessly and hopelessly across an area swarming with ghouls. Without a fixed destination in mind, the chances of surviving the journey are slim. Use your radio to discover the nearest haven. If possible, try to communicate with the outside world to confirm that this destination is indeed safe. Always have a backup destination, in case the first is overrun. Unless other humans are waiting, and unless constant communication is maintained, you may arrive to find a gathering of zombies waiting hungrily at the finish line.
