(Salem, OR) -- The Oregon State Fair opened this weekend under triple-digit heat, forcing extra precautions for both visitors and livestock. Future Farmers of America participants say animals are being kept cool with fans, water mixed with electrolytes, and even wet blankets before judging. Petting zoo staff are also watching closely for heat stress, giving goats, pigs, and sheep shade and buckets of water to splash in. Fair organizers set up air-conditioned buildings and first aid stations for guests, reminding everyone to bring water and sun protection as the fair continues through September 1.
