One thing about reducing the total mileage to be travelled over the six or seven days, is that it gives you time spare to see things that you might come across by chance. Here's an example I came across coming back from a 19 night lap of Germany I made last September. It came about totally by chance in France, miles away from where I had been in Germany.
Riding along, I came across some official looking brown French tourist road signs, telling me I was in the neighbourhood of the 'Maginot Line Aquatic'. I had no idea what it was, though had enough of an idea to know that the Maginot Line was a string of forts and aquatic would suggest that they were perhaps unusual enough to rely on or use water as a part of the defence strategy. In short, enough to justify a short detour to see what there was to see.
An hour later, I'd learnt enough to at least understand the basics of what I had tripped over by chance, had a break and could continue on with my day. Yes, it's 'In foreign' but just about understandable with the simple pictures and a bit of imagination.

The French like their 'Routes', which are (as the name suggests) tourist roads linking together things that are perhaps worth seeing. Whether, as in this case it's aquatic based 20th century forts or if it's fortified medieval churches or just a pleasant drive around some attractive villages, they are sometimes interesting enough just to turn off the road you are to see... but only if you have time.

You can usualy Google up enough information to tell you something vaguely interesting and / or offer up an explanation of what it is you are looking at or had trundled past. It's how I found out what the figures on the huge American memorial represented.... I cheated.... I Googled.... 'Chateau-Thierry memorial figures' and up popped the answer. It was easy enough to guess without Google that they were allegorical figures of some sort; Google filled in the gap, that they represent the two countries, America and France.
