Fourth District Alderman Frank Pelson, 47, awoke with a start Monday night, interrupting his recurring zoning dream. 'It was the third night in a row,' Pelson said. 'I'm sitting at my desk, drafting my proposal for the construction of a municipal pool near Franklin Park, when my inbox is besieged with angry petitions from residents who object to the traffic that the public recreational facility would generate.' Pelson said the dream always ends the same way, with him experiencing the sensation of falling out of his office chair into a 60 percent business, 40 percent residential abyss.
