Since you may end up at a shelter you would be much better off recognized as one of the individuals in charge of the shelter rather than one of the poor helpless victims. If you become involved in a Community Emergency Response Team or a Ham ARES / RACES club or the local American Red Cross or even the National Guard you will be quite busy helping others but you will get first access to aid and supplies and will be much better prepared than nearly anyone else and you will be a member of a larger team that will support you.
