Here’s a comprehensive guide as to where in the Western Cape those two and three letter C codes belong. Why not print it out and take it along on your next (Western Cape) road trip to amuse the kids, the wife, or the (intelligent and literate) beagle? It’s also useful as a tool to work out where hitch-hikers want to end up.
From this map, you can see how the curse of generally poor and overly aggressive driving has leached from CY into CF. CF is a particularly thin area, and thus it seems likely that CL will soon be affected. They’re already mostly drunk on the heady mix of fine wine and Afrikaans in Stellies, and I fear that the curse of the CY may be altogether too much for the roads to handle.
