My packing list was organized by how it was carried to our starting point and during the trip. That is, because of weight restrictions, some items could not be put in the bike bag. Other items were things I wanted during flight. Because we planned to return to our starting point in Meaux, we were able to leave our bike bags, suitcases and a fresh change of clothing at the hotel there. So this list seems to duplicate some items, but I compiled this this way because I needed a checklist to make sure key items ended up where they were supposed to when we departed from Meaux on our bikes.
