    That link sucks. It says I have to be a subscriber. I think not.

    You should be given free access to a limited number of articles (at least 3 a month). If you haven't exceeded that number, I presume that you can somehow dismiss any popup attempts to sell you a subscription.

    Here you go, Ken - probably a more authoritative source anyway:

    Lots more detail in Wikipedia:

    Cool

    If you traveled from Cambridge, MA to the top of Pike's Peak, you would weigh 0.15% less due to the change in the gravitational constant. So if you weigh 200 pounds at sea level, you'd weigh only 199.7 pounds. Probably a lot less if you hiked!

    Thanks for the new link. Yeah, it's good to know the pound is still 16 ounces and my yard stick is still good. .

    I've got your back, Ken; my father was a Texan (west Texas).
