I live in Bad Neustadt (Bayern, Germany) and discovered OSM at 2010-02-28 while reading about OSM activities for Chile. Then I saw that the street where I live was missing in the map. That's why I started mapping and tagging.
Currently I am trying to organize mappers in Bad Neustadt area - see Talk:Bad_Neustadt.
I'm also mapping in the region of Fürth because that's my place of employment.
