[AT] Scrap iron

[Dean VP]

John:

It's not the weight of the material, it's the weight of the water the hull
is capable of displacing. :-) 

We had long sections of an I90 floating bridge fall into Lake Washington out
here a few years ago. The concrete pontoons didn't fail; they filled with
water and sank taking the bridge with it. But thanks to your federal tax
dollars, a new I90 bridge with more lanes was built. I have often wondered
what commuter opened all the hatches just before a storm!  :-)
