Boxford police Lt. James Riter says he was responding to a call for loose cows on Sunday and spotted them in a front yard.
Riter says the herd high-tailed it for the backyard and then he heard screaming. He says when he ran back there he saw the cows had chased off some young adults and were drinking their beers.
Riter says the cows had knocked the beer cans over on a table and were lapping up what spilled. He says they even started rooting around the recycled cans for some extra drops.
Riter says the cows' owner and some friends herded the cows back home.
