When the ground is flat and there's nothing to stop the wind, outside items can be blown around quite a bit. I regularly go out onto my patio and pick up the furniture and put it back where it belongs.
My poor wind chimes were a mess this morning! I've already untangled them at least once since I put them out for the summer.
This time when I untangled all the lines I could tell that some parts had been torn off. I'll go back outside and check the lawn and see if I can find them and maybe tie them back on.Meanwhile, the chimes are back up and making pretty sounds as a light wind is blowing. I'm going to try and be a bit more proactive and take them down the next time that wind begins to blow.
