I am actually cycling in the Czech Republic right now, but slept tonight about 20m over the border in Germany. Definitely feel now like this tour is coming to an end. Still a good week to go.
I've had the fries with fried cheese in the Czech Republic. They also didn't salt the fries, like sometimes in Belgium, haha. The supermarkets along the border here in the ore mountains absolutely suck, they're all some 'duty free' type shops for the Germans coming over the border to buy something cheap. Handbags, liquor, cigarettes, huge packs of Haribo. Was not able to find any joghurt for my müsli, so i will have a snickers for breakfast.
Did you visit some Czech bunkers, I just remembered that last time I discouraged you but now I looked in this map https://mapa.opevneni.cz/ and realised that there is quite a lot of interesting things you may want to see.
