Cows have 'relations' on Pa. parkway RAYBURN, Pa., June 3 (UPI) -- A pair of bovines slowed traffic on Pennsylvania's Parkway West to have "relations in the road," officials say. Last week, a pig ran out onto the parkway, causing traffic delays, and on Friday, it was the cows' turn, the Pittsburgh Post-Gazette reported. A bull and cow were seen at the intersection of Routes 28/66 and Route 85 in Rayburn, "having relations in the road," said Trooper John Corna. "It's right in the construction zone so it's making a big mess out there," Corna said Friday. Police had to call in Pennsylvania Farm Bureau personnel, who coaxed the animals into custody. "We've had cows hit by cars before ... this is a first in my career," Corna said.
