I just returned from 10 days in the Bordeaux region, actually nearer to St. Emilion, for a biking trip in the French countryside. It was awesome, and I'd go again in a heartbeat. The best biking I've ever experienced quiet country roads, beautiful scenery, charming and friendly people everywhere, and great food (naturally).
