How do you prevent damage to the systems from rodents, dampness, birds and spiders, etc.? Hopefully these systems aren't stored near any cedar shavings used for stall bedding, as the fumes from the plicatic (sp?) acid in the cedar can damage any copper used in circuit boards, etc. Does anyone know if the abietic acid in pine shavings/dust causes similar problems? R. D. - I don't use cedar or pine shavings, just plain wheat straw. The temperature varies across the year. The computers are in wooden boxes, not cedar or pine, and the inside is covered with a black plastic that rodents don't chew on. They have been in the barn since the summer of 1987. I think they're all intact. Have to see this summer. Murray--
