On Monday we had the first OSM meet-up in the Johannesburg area http://wiki.openstreetmap.org/index.php/South_Africa/JHB_Pub_Meet.

I decided to do some mapping on the way there, namely to fill in any residential roads missing in the Kyalami area. Turned out to be another 60km+ of cycling in hilly terrain.

Turns out that I should think twice before returning to fill in the tracks and footpaths :
