Youre missing a few middle phases.

Phase one; days 2-5 Not riots, but lawless looting and pillaging en masse.

Phased two; days 6-15 Govt 'provides' (seizes and rations) food at central locations within the cities.

Phase three; days 15-30 Govt workers start to hoard the food rather than feed the masses.

Phase four; Some city dwellers begin to venture out into the country side to forage and gather and pillage. But the country-folk, including the country law enforcement repel them with deadly force. There will be NO large-scale groups of of city dwellers moving out into the country side. Expect groups of 4 or 5 MAX. Non-Related starving people can not organize themselves beyond fighting and killing each other for immediate needs.

Phase five; Military used to sweep country side to confiscate all food. Military patrols begin to go awol and join in with the people who actually have food and weapons.

There's more... but the key is that you have to survive through phase 3 and you MUST be out of the city PERMANENTLY by midway through phase one, or you're doomed. You're truly going to have to be GONE within 72 hours of the first grocery store lootings in your area.

So the question every city dweller should ask themselves is this... Do I have a day 2 plan for my family including a packing list, a route plan and a destination where Im expected and will be welcomed? And do I have enough fuel to get there or some kind of commodity besides US dollars to trade for fuel (Gold or Silver)?
