I found this by accident, happily. Please put me on your list. I have been to some of the places you featured and am having a bout of nostalgia. I thoroughly enjoyed this lesson.
Don't leave us hanging...tell us where you've been. My guess is Paris. I'm dying to go to Conques myself. I loved Vezelay; what a wonderful hill town (and great food, too. I can still taste those escargots!)
