Needs Must.

As you can see from the photo below the snow has finally arrived here ( I can hear you all now 'that's not a real snow fall').

The sub-zero temperatures have caught out the University where we are currently doing our training, the room we use is really cold and only has one socket the wall heater cum AC unit is at one side of the room (right) and the laptop and projector on the left. So it may not be pretty (or up to UK H&S standards) but as the title says needs must !
