I've lived in Oklahoma (damn near dead center of toronado alley) and I have never even seen a real live toronado in my whole 35 years of life. Truth be told, I get damn tired of the TV stations "live in fear doppler" they are quick to pull the "possible rotation" trigger if it so much as rains. It really gets tiresome, it turns into the boy who cried wolf.
I have more fear of being attacked by well fed pygmies wielding light sabres than I do of getting chased by a toronado.
