Whenever and wherever we travel I try to bring back something for my tray of treasures. This contains all sorts from a chunk of Amethyst and a Desert Rose from Southern Africa, various pieces of coral and driftwood, seedpods (don't tell customs!) sea urchins and uncategorized pieces of rock from Australia. Amenites and Belemnites from the Jurassic coast and my favourite piece a spike from the Old Ghan Railway Line in the Simpson Desert! My tray of memories and treasures!
