“We have absolutely no idea how or why these little critters would go out on this bridge,” Church said. “The only thing we can figure is it happened at night and they were unsure of their surroundings. Once morning came, they were too scared to walk back where they came from.”
Church called associates and brainstormed how to get the animals down. Freeman kept watch over the animals, while the deputy handled traffic.
Byron Kinn, surface superintendent for Signal Peak Energy, came to the bridge, checked out the situation and said the mine had equipment that could reach the animals. Mine boss John DeMichiei signed off on the plan and the goats were rescued by about 1 p.m., Church said.
