Prison would probably be far better. In prison they have to give you so many square feet of space and regular access to food, water, sanitation, and medical services.
Well, for what it's worth, they're now diverting buses from the Astrodome to Huntsville, TX.
If you're not a Texan, you wouldn't know this, but Huntsville is where the Texas Dept. of Corrections is located, and a number of our state prisons are there.
I'm sure they'll be putting the evacuees in better digs than that, but I did wonder for a minute.
