Hi A1,

I finally figured out this MIME thing.  Pretty cool.  I'll send you
some sax music in .au files next week!

Anyway, the attached image is really too small to get a good look at

http://www.1one1yp1anet.com/dest/sam/graphics/map-arg.htm

Then again, shouldn't the CIA have something like that?

Bill
