I love looking for shells, even now...especially when I'm travelling up north. I feel like I'm a treasure hunter when I find an especially nice one! These days I don't usually take them home, though, except if they're exceptionally nice. Some of the most beautiful ones I've ever found were when my family and I did a camping trip up at the Ningaloo Reef near Exmouth...there was a small deserted beach littered with perfectly-formed shiny cowrie shells.
No. I used to as a kid but I don't really have anywhere to put them now (small house and 2 little kids- not a great combo for having lots of small fragile things) and I don't go to the beach much anyway.
I used to until one day I thought, "Gross! What is that smell?!" I had accidentally brought home some sea creatures, which I had obviously killed as a result. Good one, Vee. I was six at the time. Scarred me for life.
