Wow, brings back memories of when I was a kid in the 70s at the Hume Weir Caravan Park, there was two old guys that ran the Boat Shed there and they had some old baths full of old yabbies.  We used to buy them and they would always give them to you in an old metal ice cream container.  The big round ones that they scoop ice cream from and put in cones...

Nothin to do with your post, but good memories for me.  Also Hume Weir Milk Bar had some Pins and this is where I used to play KLONDIKE
