Take a Duck, Leave a Duck — Imagine stumbling upon a small collection of rubber ducks, perhaps in a park, a library, sidewalk or even a local business. A sign invites you to “Take a Duck, Leave a Duck.” The concept is beautifully straightforward: if you take a duck to keep, you’re encouraged to leave another one for someone else to discover. It’s a spontaneous act of kindness, a mini-treasure hunt, and a guaranteed smile-inducer.
