A very close friend of mine is the former owner of Bryan's Harley Davidson in Moore, Oklahoma. He told me once that over the years tornado's did some type of damage to his dealership 19 times. One of their popular T shirt logo's featured a tornado!
I used to spend quite a bit of time in Springfield, Missouri - a supplier's facility was located there. Tornado's scared the be-jesus out of me more then a couple times while in Springfield.
I guess those of you who are residents in the tornado alley area get used to the threat just like those who live near the Gulf of Mexico get used to hurricane threats and those who live on the west coast get used to earthquake threats.
A few years back I was with my brother-in-law (who lives in San Jose) attending a Giants World Series game in San Francisco when an earthquake hit and leveled an elevated freeway we had just traveled across. That sucked...never care to experience another earthquake!
Anyway, just a bit of rambling...
I am glad that EVERYONE who lived in the area hit by tornado's the other night stayed healthy!
