Gainesville participated in the 10th annual National Dump the Pump Day on Thursday to promote public transportation as gas prices climb over the summer months. “The 2015 National Dump the Pump Day is a day that encourages people to ride public transportation to take them where they need to go instead of driving a car,” Phillippa Lewis Moss, director of the Gainesville-Hall County Community Service Center, said in a statement. Public transportation, such as the Gainesville Connection bus system, is a critical part of the local economy, Moss said.
