My sympathy goes out to those affected by the tornadoes in Oklahoma and other parts of the Midwest.  At times like this, I reflect on the relatively “secure” climate of Eastern Pennsylvania.  Yes, we have to put up with the occasional heavy thunderstorm, flooding, ice or snow storm; but, overall it pales in comparison to some other U.S. sections which are hit with much more severe storms, drought, floods, hurricanes, earthquakes or wildfires.
