I did not see such a note on your suggestion to use planes. ;-)

I still stand by my suggestion: a large sphere for the ground, and one 
or more nested spheres for the sky, all centered at the same point far 
below the scene. I find the infinite horizon effects very annoying, and 
using fog to conceal it often doesn't work very well.

The same reason people insisted for ages that the Earth was the center 
of the universe.
