KANSAS CITY, Mo. -- When Independence, Mo., tornado chasers Leslie and Dean Burton take to their 1999 Jeep Cherokee during severe storm season, there's a new piece of equipment riding with them.
A dash-cam streams to the Web live video of whatever they're seeing through their windshield. And they're not alone. More than 250 chasers roaming tornado country this year are allowing anyone with broadband to vicariously ride shotgun through the biggest storm season in 40 years.
