This email keeps getting posted on these threads and my point is that there were simply more people in a very small, poorly ventilated area with very little food, water, and bathroom facilities. You put all of that together and it's not going to be pretty. Think about it, it was 100 degrees, more people in close proximity than most of the largest towns in ND without showers, bathrooms and etc.

Would you rather be too hot, or be frozen?
Not that it matters, ND folks took care of their own.
NOLA folks waited for government rescuers, and still insist on handouts.
Like they have all their lives.
