Boy, does this picture make me smile!
That's John Rana (of Who Rides a Vespa), and I assume his beautiful family, on his PX150e.
The pic is not from John's Blog though. It is from a great site he turned me on to, Ciao Vespa: You and Your Vespa.
This site invites Vespa riders all over the world to send pictures of their scoots with some commentary.
Some guaranteed smiles-per-gallon perusing this site.
Good find, John!
