One of the fun things about going to Mozambique was that the doublecab we drove up in had a GPS. The closest I've ever come to one of these is looking at ads in the newspaper!
So - although I was deprived of my new computer (I even dreamt about it one night) - I had somebody else's wonderful techy toy to play with.
GPS in Joburg is often a bit unnecessary, but it was very reassuring to have in Mozambique! We did on two occasions find ourselves on tiny dust roads that it could not identify, but even then it would give us the direction to travel to reach a specified point. And when on the roads, with signposting in short supply, it was encouraging that the GPS would tell us that we were on the EN1 or the EN6 or whatever.
I smsed the GPS co-ords to my husband occasionally, and he tracked us on google earth. I had a look when I got back and it is amazing! The picture here is from Google Earth, with Grant's labelling (and spelling!). You can zoom in much further, on the real thing.
For anyone interested, Belasse is found at 18 56.011 S, 033 12.703 E. The farm where we stayed is near Chimoio at 19 13.614 S, 033 20.522 E. According to Google Earth we travelled about 60km from the farm to Belasse.
