Coulda, woulda, shouda... second guessing is pointless in unprecedented situations. Evacuate Houston? Have you seen rush hour there? There are changes that can be made, both short and long term to reduce the impact of such storms. The political will to do so is in question.

In any case, what we see in Houston are people at their best, trying to deal with a natural disaster. Just be careful who you donate to. This will bring out the crooks as well.
