IMHO if lives in an area relativly free from natural disasters, and not a likely terrorist target, then the main risks come from natural disasters and terrorism in distant places.

An area not prone to hurricanes could still suffer fuel shortages due to a bad hurricane destroying oil industry assets thousands of miles away.

An area not at real risk of terrorism could still suffer the effects of terrorism thousands of miles away, resulting in oil or food shortages.

A bad ice storm in Canada could disrupt power supplies in the Southern states.

The main preps would appear to be stockpiles of food,fuel and other supplies, growing your own and not being over grid reliant.
