One of my friends lives in Houston. He is a new home owner and just bought his first house ever a year ago. He actually bought flood insurance and all of his Houston friends told him he was wasting money. All his friends that said don't bother it is a waste of money have flooded. His house is dry. the flood waters were within a few feet of his front door but never got any higher and have been going down. He figures that flood insurance was the best insurance ever. He does of course realize flood insurance like any insurance is not like buying "insurance" from the mob, it does not prevent the damage but all his friends without it flooded, and he didn't so it must have worked!
