This what we in the northern states should be preparing for. These people are not going to be able to return home, we do not want refuge camps anywhere in America, that will only be even worse.
Perhaps this is a test for America to see if she is indeed worthy of caring the torch of freedom. Let freedom ring, make voluntarisms work! Lets roll!

Contact local churches, shuls, (synagogs), and business organizations. they will already have the structure in place to work with rather then building it your self. The key to making this work is some kind of filtering system. I imagin that this might be a great oppertuniite for illegal imigrants, and crimnals to move to the usa. So people should be vetted by say, being passed through a number of check points, and if they check out as ok, finally being cordinated with a family. we don't need now strong, self supporting families or homes, being unbearably taxed by having allowed a criminal element or unsocialble person into the heart of their home. For these types, other services must be provided by the government.
