I think they put too many people in one place for this to work for more than a few days. But at least they have power and toilets and food and water.
If I were king I would have sent a few thousand to many locations...let them ease into the local population and be diluted by the people around them. Get jobs and hopefully stay....and change their previous lifestyles.
Houston is going to shine thru this.
It's the first city that I could think of that has it all and the people to pull it off with class.
Mark my words.
