Becoming familiar with your surroundings. If you know where you will be for the pole shift, get used to the lay of the land. Also get used to where any supply sources may be. This would make it much easier to find your way around later. Choosing alternate routes then will be easier also, leaving you more mental space to cover your butt against attack from gangs. The land may change in many ways, but you will still have a better idea of where you may be going, and how to get back.

Expeditions for supplies will bring danger, but are a must. If you don't do them, you don't know what's going on in your neighborhood, and the situation can be even more dangerous.
