Verneukpan / Augrabies round trip - Route advice

[silentbob]

Ok, so heard of this ride that is being planned. The route so far is something like this ...

• Leave Johannesburg and head towards Parys and then onto Petrusburg via Vijoenskroon; Bothaville; Wesselbron; etc.
• Once hitting Petrusburg, swing North towards Verneukpan & carry onto Augrabies.
• Then head back to Johannesburg via Upington & Kuurman

So, what we need some help with it details on lekker dirt roads to ride. Anyway have some ideas / tracks / GPS Co-ordinates?
