Covered the neighbourhood east of Gräulingerstraße. This is full of one-way streets, only some of which are open both ways for cyclists. Also covered the area around the church in Gerresheim and made the connection south to the L357.

I am still puzzled by how the GPS works: sometimes it is exact enough to show properly two different tracks when I went up a street and down again. Then again, where I rode around the market place, a nice square, the result looks anything but a square. And sometimes it gets confused and tracks me 50m off the street only to jump back on the street shortly after.

I wonder if overhead electricity for the tram can be a problem.
