Evacuations are a complex part of any disaster.  This is one of the largest and most stressful complications in any disaster situation.  No matter how much you have prepared as a community, there are many things that can go wrong.  Evacuations are also wrought with many cascading dominoes of activity (transportation, accountability, re-entry and many others).  It is worth taking time to learn from other community lessons around the US and how you as a disaster leader can best help manage this crazy situation.
