Hey Sproul....For all the talking that's been going on about screams, it seems evident that none of you have ever heard a Great Horned owl scream at night. The fellow who said it was a hoot owl was very close, if not correct. A Great Horned scream will put stuff up your back that will take Charmins to get off. The first time I ever heard one it made my hair stand straight up, gave me goose pimples and made my eyes water. Scared the living daylights out of me. I was about 12 yrs. old at the time. That's where your screaming at night is coming from.
