I have never closed due to severe weather, but I suppose in extreme circumstances such as a prolongued power outage, I would have to. Otherwise it is up to the parents and I will not be taking the kids out in very bad weather. In fact, if there is freezing rain or some other severe weather, I will just keep my son home from school so that we don't have to get him to and from the bus stop (well teh buses will be cancelled anyway).
