CUMBERLAND — On opening day of the Cumberland County Fair Sunday, Gael and Gayleen were two unhappy Nubian goats. The 5-month old pair, with their trademark woe-begone drooping ears, emitted mournful bleats as they stood tethered outside the arena while inside their owner, Phil Cassette of Saco, showed off a potential champion before the judges. Suddenly Gael made a break for it, snapping her collar and running free while Gayleen, still tethered, sobbed even louder. Some one shouted “goat on the loose” while some else grabbed Gael by the leg just as she was about to disappear around the corner.
