When we moved into our house here, we discovered the previous tenant had abandoned a litter of rocks in the house. We put them outside (it was spring, after all), but they were petulant, spoiled house rocks, and their whining and door-scratching kept us awake, so we gathered them up, took them down to the creek, and set them free in their native habitat, to sink or swim. I’m surprised to hear you have similar problems in the Keystone State.
