years ago we had major bushfires down the west coast, but being a long way from town I thought more of it. went out to wash the (shiny new white) bike, walked back into the house and happened to look out the window, wondered why it was snowing on such a nice summers day and realised it was fine grey ash, the wind had blown it from the fires about a hundred miles away and covered the whole of the city in a fine grey powder. went out the back and sure enough, white bike had become grey in a matter of minutes
