Thank you all for the nice comments.

I do not have a GPS. I use maps and google earth. Normally when I go on trips like this I give myself waypoints in my head. These are usually the bigger towns or a landmark like a mountain. From Warrenton my next waypoint was Postmasburg. I had 3 hours to get there. I know for a fact that there are a lot of gravel roads (to the farms) other than the normal tar routes in the Northern Cape. I just ask a local in the small towns between my waypoints for a gravel road to the next town. The northern Cape people are extremely friendly and helpfull.
I love it but I know in terms of accidents etc its a hell of a risk. Should something happens I will probably be a piece of biltong by the time they find me. But they will find me with a smile on my face.

I do not want to spoil your Boegoe 2009 trips so I will not give out tips ets for your Bash planning.

Go and explore.
