You've seen them on TV, and you know they gather important information about severe weather that can save lives. You think they might be a little bit nuts, and you wish you could be one of them: Storm Chasers, the guys and gals who go out of their way to find and photograph tornadoes up close and personal. Now you can give it a try, by signing up with Storm Chasing Adventure Tours. For the past five years, severe-storm expert Todd Thorn and his band of merry madmen have been providing tornado tours to people from around the world who are in search of the ultimate adventure vacation. Last year, the tours sighted seven tornadoes and dozens of storm cells; this year, Storm Chasing Tours has added a two-way satellite Internet system in the tornado van for full-time, real-time weather-data access. The storm season starts in May in Texas and Oklahoma, then moves to Colorado and Nebraska in June and July, and Storm Chasing Adventure Tours has ten tours planned to catch as many of them as possible.
