Huh.. I never thought of it before but I think I accidentally trained Penny, the golden retriever we had as family dog when I was growing up, to hunt for sea glass. I praised her a couple of times when she found a nice bit, and thereafter whenever we went for a walk along the shore she'd run around and come back with a bit every few minutes. I just thought it was a dog thing...see shiny, pick it up and show it off.. you know. She'd do that with drift wood and sea shells too... I totally could've done some fun wire wraps and muddles if I'd known as a kid they were a thing!

Never knew creek glass was a thing though, but I should've realised it would be. Live and learn.
