From what i have been told, if there is an emergency such as an earthquake, terrorist situation, or some other threat that made it impossible for parents to pick up their kids, we would have to stay put. I would imagine that as parents managed to arrive we might let the teacher/parents with the greatest need to be with/find their own kids would leave as the # of students dwindled. I guess it has to do with the idea of schools as "en loco parentis" ( have I mangled the Latin? :-) Sorry!) I'll try to remember to find out details next week.Sue
