I was just getting into bed, when a heard a the sound of dripping water. Yes one of my windows is leaking at the top of the frame, It is not raining that hard, well maybe a little hard. So dress and examine... Sure enough the roof gutter is overflowing just above the window. Water running down the outside of the south wall.
I know what it is... It is the crows, and or the jays, they love to hide nuts in the gutters. Well I ain't cleaning gutters in the middle of the night.
