No Julie, you are not going mad, and I would believe what you saw was an Elephant, what else could it be you saw what you saw, I live in Yellowknife Capital City of the Northwest Territory Canada, and about the same time you saw your Elephant in the Carnival Parade we had an Elephant in our Canada July 1st Parade, a very good friend of mine who was The Director of Education at that time another Welshman took a wheel barrow and collected the deposits of that Elephant and he used it in his garden to grow massive Zucchini's, Julie that is the truth only believe in what you see, best wishes Will.......
I have many, many photographs of Morriston Carnival in 1988 and not one sighting of an elephant or a zebra or a kangaroo.
Anybody wishing to see any of my 100,000 images can easily email me via MrMorriston@gmail.com providing they are not already on display on my facebook site.
However, if I haven't got a photograph of something, I will not be able to magic one up out of thin air.
