Enjoy the descriptions of the weather and of Minnesota, which the author obviously knows well. Don't be put off by any 'preachy bits'. Quite a visual book, which would make a good film!
Todd was already soaked, but with any luck they could make it safely to his car. As he took a step forward, however, a huge blast of wind blew him off balance. Oh, my God, thought Todd, is this really a tornado? ... suddenly a figure in a hooded yellow slicker emerged out of nowhere, someone small, someone running desperately along the Stone Arch Bridge. Another fool, thought Todd, as Mark and he charged on, their heads bowed against the torrent. Someone else looking to get killed.
