I'm not particularly sure I like caves. They certainly are a wonderment - the opposite of a mountain deserves our awe and interest - and I quite like to be a tourist in them, but they always make me quite uncomfortable. When I was a little girl, perhaps four years old, we visited some caves in country Victoria (Buchan Caves, perhaps) and my Mum turned to see little me with my red cardigan pulled over my head protectively, as if I knew even then the potential of caves to collapse on those who dared venture within.
