presuming that bugs dont like the heat im inclined to leave it covered as best i can with an imersion chiller poking out of the top then chill on my return.
just when youve got a day off some git screws it up for you. typical!
if this goes off im making her buy me 30 pints of brown ale as compensation

mind you as its so cold outside ive done the boil in the kitchen, the house stinks now, i can counter the grief i get with the son/doctor point hopefully.
cheers
