I would expect a very, very large die off in the cities in days or weeks.
Those of us that have spent years and have experience in subsistance level feeding stand a pretty good chance.

Lucky us, we have group camps already setup for the displaced. One at the old Richards Gebaur airfield- airport in Belton, Mo and the other at Fort Leavenworth. Need food, water, shelter or clothing? Go to the camps. You will never go home. Courtesy of FEMA.
