Radio Smart Talk for Friday, October 21:

What drives a man to get as close to a tornado as he can without being swept away?  Is it science or just the rush of adrenaline.  Maybe it's both.  That's a question we'll ask Reed Timmer, star of the Discovery Channel's Stormchasers TV show on tomorrow's Radio Smart Talk.

Timmer is a meteorologist who leads three teams of scientists close to and into tornadoes to capture video footage and measurements.

Timmer will be speaking at Penn State Harrisburg's Capitol Union Building Saturday at 8 p.m.

Also, the death of Libyan leader Moammar Gadhafi could mean an end to the hostilities in that country.  We'll discuss what's next for Libya with a local mideast expert.
