Re bottles, if I was doing it this year I'd take an extra one for the first night. Water was hard to come by in France (I couldn't find any) and Germany might be no better.
For the next time: in France any cemetary will have a tap.
Yes I knew that but my route planning didn't pass any cemeteries! I had a good look round the back of three or four churches. I saw wheel tracks, but no taps!
