Very interesting DJ, That's 6kms from Bloem. They didn't have Google Earth and GPS back then, so Bloem (about 170kms from the current Centroid) is not a bad take. Considering the rendition of Maps were very rough back then and borders shifted constantly.
RobC, Good Idea to explore using Barkley West as a base.
You are based in the OFS so presumably not too far. Us Gautengers are not too far - around 450kms away as the crow flies.
I would be keen to hook up for a reckie around and plant a WD centroid marker. This weekend is a bit soon for me but next weekend or the one thereafter would suite me better.
The tar road to Barkley West from Jhb is very boring, so I'm studying some dirt routes to make the trip more interesting.
Who's keen to explore the surrounds and plant a marker?
