The building I live in was constructed in the late 1800's or very early 1900's. There is a ledge, maybe 18 inches wide, that runs along the entire front of the building, right under my living room windows. It serves no purpose except as an architectural design element.
It is raining today. If I crack my windows just a bit, the sound of the rain hitting the ledge reaches my ears. It's not as good as rain hitting a tin roof, but it will do.
Later I may have to doze in my recliner next to a window and just listen. The sound of rain is good for the soul.
