When I was younger I would fling my BMW 5-series (and younger still my Honda motorbike) down this hill and around the bend in the photo at over 60 mph, trusting to luck that there wouldn't be a tractor around the blind corner.
This is a shot of the R719 and the railroad that runs parallel to it about 18 miles south of Bothaville in the Free State, a couple of miles south of our camp at Schoonspruit/Skoonspruit.
This photo, looking to the west from the eastern end of the survey area shows the grid of lines we left across this area. When you look at the Google Earth satellite view you can't see any tracks so no lasting damage, apparently. Also, no new mine shaft so it looks as though our client didn't find what they were looking for.
Alfalfa usually has the highest feeding value of all the common hay crops and is most often used as feed for dairy cows because of its mix of high protein and highly digestible fiber. This alfalfa field cost our client more than the maize fields even though it was less than an eighth of the survey area where the corn fields were about three quarters of the survey area.
On this survey we were using four Failing Y1100 vibrators mounted on International 6x6 trucks as our energy source. In this photo you can see the four vibrators shaking the ground and carving their way through the maize. In the foreground a spare fifth vibrator sits idle, ready to go to work if one of the other four breaks down. In the background are the Schoonspruit/Skoonspruit grain silos.
As I mentioned yesterday, one advantage of flying in a helicopter that has no doors is that your can get shots like this one, looking straight down onto the field of maize (corn) we were flying over. I recall I had to lean out quite some way to avoid getting the skids in the shot.
