As the last big holiday weekend of the summer gets underway, police across the Coastal Empire will be ramping up patrols on Savannah area streets and highways. “We’ll have police out all weekend, but obviously if you’re out drinking and driving, we’ll be looking for that,” said Savannah-Chatham police Lt. Greg Mitchell, commander of the department’s traffic unit. Friday night will see multiple law enforcement agencies join together with the Governor’s Office of Highway Safety for the Hands Across the Border operation.
