Davey,
If you email me or phone the office and tell me or my pa what you are covering, how long you have to talk if there is any specific angle, or maybe the title of your talk, I can either lift an existing presentation or stiick on or two slides on a cd for you. I must resist the idea of going to Cheshire though as (according to some dozy DO in the fire service there) if, in hotels, you do not have plans on the back of bedroom doors even in straighforward corridors with escape at each end, he will have to explain to the coroner's court why all these people died. ( Personally, I think when the arguement gets to that level, it has already been lost and it is an admission that there is no valid arguement but merely a whim of a dogmatic dinosaur. So Cuba would be preferable to Cheshire.
