I did some mapping on the Garden Route years ago. When I later went and looked back at those communities, I was disappointed to see that little work had been done since my own edits long ago. And in general, much seemed to have been added by other foreign overlanders like myself, and not any kind of local OSM community. I wondered if this is because those demographics in South Africa that are affluent enough to be interested in nerdy tech things like OSM, have also grown up in a culture that always warned them of idly walking around towns with phone in hand?
