1. Storm-chasing tours take place in Tornado Alley in the US, where meteorologists and experienced chasers lead participants hoping to see tornadoes up close.
2. Tours last several days to weeks, with vehicles equipped with technology to track storms, though participants may drive long distances without knowing where they will sleep.
3. While the experience can be exhilarating, it is also exhausting as chasers compete for limited hotel rooms and may have to share beds, and the chances of seeing a tornado are slim despite severe weather.
