I'm not assuming to speak for hypnos, but I've long considered CA to be a potential problem, even when I lived there. High population density areas which depend on food transport from the central valley and fuel from southern/central CA wells and refineries. If the food/fuel lines are disrupted, where will the people go? Some (many?) will not be able to leave the state via automobile and that will create the proverbial "golden horde" which will be looking for food. In southern CA, the mountain passes to Nevada/Arizona will remain open in winter which is a large corridor for the refugees. Northern CA pass may also be blocked with snow in winter. In summer months, the southern passes will be hot zones due to temperature and low water supplies, while the northern passes will be both temperate and have plenty of water. If a (food/fuel) crisis lasts more then a month, starvation and rioting will begin to reduce the population. Reason to move out of those high pop. density areas, now. Another concern is how the national guard and police forces will respond. If they attempt to contain people, they will be eventually overrun unless they can offer food and shelter. Much depends on what aid may be coming from outside the state.
