While tabletop scenarios can be fun to discuss, useful in preplanning and help provoke thought, without realistic specifics or parameters they can become nothing more than fantasy.

I think most of us like the mental stimulation of “what if”, but this scenario seems to more along the lines of sweeping hordes of unstoppable zombies invade your community, now what do you do?

I think that unless there is logistical reason such geographic or conditional causes of single point evacuation, most residents will disperse in multiple directions. Short of a major weather event (hurricane, flooding) affecting a region, most real world evacuations are local events. Even in a regional event such as a snow or ice storm, evacuation is a local or a series of isolated events with most residents hunkering down or relocating to family and/or friends outside the affected area(s).

I think rather than speculating upon what seems to be a never-ending scenario, we look to real world examples of local and regional evacuations (there have been many in the last 5-10 years) and analyze what worked, what didn’t and how we may incorporated those experiences into our disaster planning.

Just my 2 cents-
