Your junk is someone else’s treasure.
Julian Pattison writes (in LotsOn) “Tomorrow (Sunday 22 August 2021) is White Elephant Day. If you have stuff you don’t want, put it out on your doorstep, and see if someone else does! Then go for a scavenging walk yourself, if you fancy. You will need to take back into your house anything that doesn’t disappear. Please do not put out unwanted children, pets or partners!“
Please don’t pick up garden ornaments, or stuff kids might have just left out while playing! Knock if in doubt.
