Dublin Police Services has created a motorcycle unit to combat ever-increasing traffic problems. Officer Bruce Rank, 49, is on the street riding a BRAND NEW POLICE HARLEY DAVIDSON purcahsed from the Vallejo Harley Davidson Dealership. Lt. Dave DiFranco said Dublin Police Chief Gary Thuman decided to bring in the motorcycles because of the city's growth, which is expected to be tremendous in the next five years. "Dublin is expanding, and we have so much more traffic. We have become a suburb more than a small town," DiFranco said. "We have to change with the times in orderto be effective, and this is just part of the process." An 18-year veteran with the sheriff's office, Rank has a personal 1997 Harley Davidson Road King and is a member of the Blue Knights, a world-wide law enforcement motorcycle club. "It is one of my only off-duty pleasures," he joked. "It is a whole different realm. There are a lot of hazards that require a lot of care and a lot of training," Rank said.
