County Worker Mark Johnson Wins $50,000 Steve Martin Award, Chance To Play Banjo On 'Letterman'

A job reviewing storm and flood maps for the local county government office is hardly the kind of thing that makes you a hard-partying "wild and crazy guy." But for 57-year-old Mark Johnson, his day job as the emergency management director in Florida's Levy County has allowed him nights to pursue banjo playing -- and get a big check from actor-director and banjo-lover Steve Martin.
