Well, all, my hubby and I have decided to close our pool like the rest of America and save that money we would have spent on heating. Well, actually, we're spending it on other things, but you get the idea.

I have begun the process of putting the insulating sheets on the pool anyway (using waterproof 'duct' tape), since I've got them and I do believe they will help in the long run. We'll see if our gas bills are any less next year...

Thanks for all the input.
