I just spent 2 weeks in this region and there are some rich picture taking oppurtunites in the Bordeaux region.
Bordeaux city itself has some wonderful architechture (historic). The Buildings, bridges and general ambience is wonderful. Pictures everywhere!
I have made a mental note to return to one of the large churches there with my LF kit and a few boxes of film, maybe a UK excursion on a cheap flight direct to Bordeaux and stay over a night or 2, out of holiday season.
