Hoping to unconfuse you, Byron, the lack of much light loss due to water
depth (i.e., actual water absorption) says nothing about shading. Upper
leaves always tend to cause various amounts of shade on lower leaves, so 
they do get the largest share of the light.

"The War on Poverty created a great new upper-middle class of
bureaucrats that found they had a fine career as long as they could keep
enough needy people there to justify their existence." --Ronald Reagan

The War on Drugs gave the bureacrats assault guns, helicopters and
bombs, but they needed, and somehow magically got, far more addicts.

I often think I'm paying for a lot more government than I really want.
