Warren County Commissioner Les Trotman has asked McMinnville Mayor Norman Rone about starting preliminary talks on metro government.It’s an idea Rone says he will bring before the Board of Mayor and Aldermen, although he says he no longer supports metro.“I’ve been in favor of metro before, but over the years my opinion has changed and now I’m not very much in favor of it here because I fear McMinnville will lose its identity,” Rone said yesterday. “The city is doing things now with our road paving project and with parks and recreation, I don’t know if it will be a good fit for us anymore. But I will bring it before the board and see what everybody says.
