Well I have only seen one tornado in my life, was at the church and a tornado came over never did come down, and like dummies ran out side to look at it. A few years ago a tornado went thru a trailer park southeast of where I live, if it had been a half mile to the west and stayed together longer it would have flatend us. That trailer park still has empty spaces to this day.That was also I think part of the same big storm that hit Andover as well, tore up half that town. Funny thing with that storm it tore up a shed but did not bother anything in the shed, exsept to get everything wet.
