Well, I liked it Al but then I like smart people. That's why its good to
have the top up and to remove the water-retaining fibreglass insulation from
right beside the cold metal. What were they thinking?.
Go ahead and tell me how much water vapour a 190 lb man breathes out while
sleeping for 8 hours.
Does it change if someone is playing the banjo 100 feet away?! ;)
Seeya, Jake
