Little late to this party but, from what little study I've done, since 1979, Houston averages a flood every 5 years. Houston is at about 80 ft. ASL. Knowing that, why would anyone buy or build a house near the coast and/or on ground that's not at least 300 feet ASL? Granted, sometimes you're forced to live near your job.
We were doing some serious shopping for a new house back in 2001 when we knew we'd be moving my mother in with us soon. Living in earthquake country, one of our requirements was that the lot the house sat on would have to be cut ground not fill.
North-Central Arkansas has a history of tornadoes, but is not in tornado alley. We will be taking a calculated risk in moving there. Mountain Home however, unlike Houston, does not experience mass destruction every five years.
You're sometimes forced to take risks. Can't think of many places on this planet where you're not exposed to fire, flood, winds, quake or pestilence. You do your best to plan ahead and minimize or at least moderate your exposure to them.
With regard to fuel prices, this is SoCal. If fuel goes up 29 + the non-existent denomination of 9/10 of one penny per gallon, that's only about 10%. In this environment people hardly notice that.
