In the past few days I've spent at least four hours out walking around the city trying to map as many streets as possible in the area in live in - Stuttgart West. It's great to get out there - even if it does start raining - and explore the area around me. Once the spring and summer arrive, I'll start cycling around with my GPS and my camera as well. Exploration, photography, geography and keeping fit, all in one.
If you've not yet tried OpenStreetMap, what are you waiting for? Why not get out and explore your surroundings. Careful though, it's addictive!
