My girlfriend has two older sisters who are still in Houston. They did not leave two days ago, so there was not really much use in trying to leave through the chaos. They figured they were safer in their house than in their car. They have no guns, though they do have a few swords. I guess that is better than nothing. Their house has flooded before, so there is a real good chance that their house will flood again. One sister was sent to buy food and bottled water, it was chaos at the stores.
Prayers are in order.
