I had added Riesenbeck along general lines. For mapping I used a car and a Nokia N85 and a Nokia N79. Still missing the extension of Gelsbach on the south side of the Heinrich-Niemeyer-Straße with the Grüner Winkel. Also the Alte Birgter Straße and the harbor are not correct. I'll fix the bugs in April when a stay again in Riesenbeck.
