There was a big mayoral summit in Miami this week and while some wined and dined at places like Prime Blue Grille, others hit Halo, the Lincoln Road gay bar. Take Washington, D.C. mayor Adrian Fenty, for example, who, according to our spies hit Halo Friday night. "He sat in the corner, had a drink," says our spy. "As he came out of the car with two bodyguards, his guide asked, 'Should he put on his suit jacket?' to which someone replied, 'No, this is a bar.' He came in, sat in the corner and stayed for 40 minutes. As he was leaving he was recognized and greeted everyone cordially. He shook hands, greeted everyone and then left." Random, huh?
