FYI to those who visited Conowingo Dam: I assume since you didn't mention the Great Horned Owl nest in one of the large tulip trees overhanging the water near the center of the parking lots, that you didn't know it was there. It has one half-grown owlet in what appears to be an old crows nest, and was being attended by an adult when I saw it on 4/11. They were quite unaffected by the crowd of fisherman and others milling around. Bill Bridgeland Sparks, MD
