OK, there isn't anything left of the dead horse to beat but, I think that the scale or something may need to be recalibrated.
Here is the math that robo and I used to figure that the pack had to weigh more than the 5lbs that was originally said and that also comes to more than the figure that was changed to 7.6lbs
A full 3L bladder contains approx 100oz. 16oz = 1lb, therefore 100oz = 6.25lbs.
A 32oz Nalgene bottle = 2lb of water + .5lb weight of the bottle.
The lightest Camelbak model that holds a 3L bladder (The Rally) weighs 1.5lb when empty.
According to Amazon.com, the WMG weighs 1.1lbs
EMS lighest raincoat or poncho weighs about .75lbs
The lighest rain pants would probably run the same .75lbs
Four 1oz granola bars would be .25lbs
That totals 13.1lbs plus the:
"2 PB &J sandwhiches, 2 hershey bars, 3 bags of yogurt covered raisins, a compass, whistle, 1st aid kit, headlamp, Tyvek Map, Mirror, Waterproof strike anywhere matches, a SOLAR BLANKET, Long Sleeve Jacket... AND a pair of Polarfleece Pants, winter hat and gloves."
Which would probably total at least 1.9lbs (though the jacket alone could be more). Therefore, it is safe to say that the pack weighed at least 15lbs (though probably more) if John had the lighest available of all of the previously mentioned things.
15lbs... That's 3x the weight that was first reported. Somehow, the 5lb story just doesn't hold water, even if the bladder and bottle were both empty.
Better call Pinkham and tell them to get a new scale...
After that, let's get back to talking about things that matter.
