Guess I am asking the wrong question.  Googlepages have no extensions.  If you
use winhtttrack it adds an html extension when I run it.

The issues is if you set a site as "adult" track never gets past the I am 18
redirect.

Other fun things google does is creates hidden directories for graphics files
named after the graphic file.  Fortunately I can find those and they are
downloaded.

I figured out what works for me, but was hoping someone else had a "project"
that would get just the googlepages.
