Personally, I think Atlantic Coast is making a big mistake. I have a feeling that the listeners and airstaff are not happy about this and the only winner in this is WJBQ because it just gave them another reason why they are the dominant Top 40 in Portland.
As for Portland, Maine getting another Rhythmic, probably not at this point in time, since this is a different Portland altogether and I doubt that Saga, Nassau and Citadel will flip any of their properties, which is already saturated with their favorite format of the moment: Classic Rock, Country and AC. Can you say "Des Moines?"
