Since Rush refers to the Southern EIB headquarters as the Bunker.......
As for local hosts...there’s a guy here in Boston,Howie Carr,who’s spoken in the past about having been at least somewhat concerned for his safety...particularly because of a long-standing “thing” he’s had with one of the FBI’s Ten Most Wanted...Whitely Bulger.
Glenn Beck has talked about his security on the radio and TV.
Few years back there was a credible threat and him and his family was moved to a protected safe house. Studio was set up there for a week or so till the threat was checked/dealt with.
Can’t remember if the threat ever turned out to be real or just a very scary nutjob.
