Mary Mason is traveling the country hoping to buy a radio station. "No more just working, I want to purchase," a station, she told us Monday, before taking off for more travel. Mason says she has put a "good group together, a small group," of investors. The longtime 1340 WHAT host was unreachable to provide more details on her pursuit. Since the demise of the station's African-American talk-radio format, Mason has most recently hosted a Saturday show on WWDB 860-AM.
