I grew up in Michigan where Mother Nature is really pretty innocuous. Oh, there's a chance of getting caught in a major snowstorm, being hit by lightning or the occasional tornado but nothing that's really too threatening.
On the other hand, when I moved for a while to Iowa, tornadoes/tornados, were a real threat but taken to be just a fact of life by the locals. I shared an office with a guy from Chico, CA, who thought earthquakes were ho-hum but was terrified that weather could actually kill you! The fact that we were on the 37th floor of a 40 story building only added to his terror.
What's the big natural killer in your area that the locals ignore? Z-Man, I know that's boredom for you.
