I'm counting gas explosions this year

What is up with all the gas explosions? Has anyone else noticed the increase in gas explosions lately? The block in San Fran that blew up started my interest. The house in Cleveland on w.83rd st., and the Allentown PA explosion recently. Closer to home how about the entire town of Fairport Harbour being shut down after a bunch of explosions in peoples houses. Whats your thoughts? Aging systems, perhaps..poor maintenance, perhaps..deregulation, perhaps...i know when i go into peoples houses, the one piping system that looks the worst is the gas..its just ignored..now the ever popular corrugated stainless steel tubing CSST gas piping is having an issue..wasn't this touted as the replacement for black pipe? yeah right...read about the law suit on that stuff at my web site at http://www.gwgillplumbingandheating.com/
