snakes and alligators

I could go into extended metaphor mode now, what with the slippery dealings in the UK and the swampy ones across the pond in the USA.

Instead it might be better to ponder upon the physics of a disc world, perhaps with four elephants balanced upon the back of a giant turtle?

But wait.

Here, right in the back garden, is a turtle candidate. Answers to the name "Great A'Tuin".
