Couple of questions regarding structures in the "tornado alley":
I see that a lot of homes in the US are timber construction, is this because of the plentiful supply of timber, the lack of concrete & brick for home construction or is timber the preferred method of construction?
Is it mandatory to have a storm shelter/bunker/safe room in homes in "tornado alley"?
May seem like silly questions from the other side of the world but my limited education on tornadoes comes from "Storm Stories" on the weather channel & the ABC & CBS news feed from the US.
