For mumsnetters in the USA, particularly those states which are more prone to tornados, how common are they?
I'm a bit fascinated by them at the moment. Are they common like you'd experience a couple every 'season' or is the area of counties/states so large that actually a tornado near your home town would be a once-in-a-lifetime event? Does everyone have storm shelters built into their houses?
Hope I've made sense. Just being curious about how people and extreme weather co exist.
