Yesterday when leaving Madrid, I felt something weird on the car wheel. We stopped and saw a big screw on the tire. As these are run-flat tires (there is no spare wheel) we can still run with them, even if they loose pressure; the bad news is that we should not go faster than 80 km/h. So, we took more than 5 hours to make 400 km. I had plenty of time to sketch, until the sunset, when it was too dark to go on…
