Your NGMs as attic insulation
For all of you who may have stacks of old NGMs stored in the attic (not that I'm recommending that), I thought you might appreciate this excerpt I ran across from one of our news features entitled, "The Cold (Weather) Facts About National Geographic, dated 3-2-1977:
"Curious engineers of the National Association of Home Builders, urged on by the Geographic itself, have calculated that the magazines are just too solid, and rate an insulating factor of only about R-0.25.
Put another way, to provide attic insulation equal to 3-1/2 inches of fiberglass batting, R-11, a homeowner would have to pile up National Geographics 47 magazines deep. And that would amount to a ceiling threat of about 91 pounds a square foot."
I do apologize if anyone was using that as an argument for holding onto their old magazines.

Cathy,
...this was great!
Thank you for sharing this story, it gave me a good chuckle. I don't remember seeing this article (even though I DO have EVERY issue from 1888-2010). How can I know every page in 122 years worth of NGM's, right?
