The US is a country of extremes. Everything is big, much, and far. The climate in this country definitely fits in this description: six months ago, I could not stay outside for more than 5 minutes because of the cold. However, between May and September, it is so hot that you go from airco to airco... Moreover, it can change any minute to extreme thunderstorms with a lot of rain, flooding basements and roads.
Other parts of America are even more extreme. In the South-East, you will allways be affraid of the tornado season. The north has a combination of low temperatures and wind which makes it impossible to even walk outside. And the South-West is a major earthquake target.
