	I am trying to build up our logo using MetaFONT with little
success.  The logo has areas bounded by curved and straight lines.  I
am trying to use the draw and flex commands of MetaFONT with no success.
What am I doing wrong?  Could someone steer me in the right direction?
I keep getting the error:

! A tertiary expression can't begin with `..'.
<inserted text> 
                0
<to be read again> 
                   ..

If I leave out the `..', it gives me an error and tells me it inserted it for
me.  HELP!!!!!

Thanks alot in advance.

-Earle
