A classic car rally last July in Northern Portugal, in a wineyard zone
(Vinho Verde http://en.wikipedia.org/wiki/Vinho_verde )

The photos can be acessed directly at:

I get the feeling from the photos that this was a rally more in sense of
a promenade than a competitive rally, although there was a classification
and a winner.
