Last evening I rode my bicycle along all the cycleways in Papendorp (a commercial district under development in my hometown). While putting those cycleways on the map, I also added more detailed landuse with the help of Yahoo (and my observations). During the editting I noticed some weird looking road junctions and streets. I have to go back there anyway for the footpaths, so I can look at them then.
