I was camping with my family at Greenfield State Park in NH and we were sitting around the campfire at dusk and an owl swooped into the tree right at our campsite. I believe it was a Great Horned Owl. I didn't have my camera handy and it probably would have been too dark to get a good picture, but it sure was exciting. Another time I was getting out of my car at about 10 p.m. and I heard 2 Great Horned owls conversing back and forth right in the woods behind my house. I just stood in the driveway and listened to them as I could not see them. It was awesome!
