Hi Clive this is again a great idea for the new challenge with many possibilities. Thumb up everybody! :)

@ Jeff:  A very original start of you, more something for "thumb down", and I have a great laugh here!
Let those containers please remain closed, although if you were going to dig, I am very curious whether you would indeed see containers.
So, where's your proof, Jeff, or did you bury them yourself?

Anyway, a cool first post and shot, my friend. :D
