Humewood and Milnerton are generally the only two courses in SA that are links like, I haven't played Milnerton, passed by it a few times, but I don't believe it is anything special. Atlantic Beach up the road from Milnerton is links like and I must say I enjoy playing there.
There was flooding in Port Elizabeth in august and some of Humewood was covered in water for a period of time. The local members were worried in wouldn't be in good shape but the greenkeeper did an excellent job.
I'm not sure what type of grass is on the greens but it is quite prevalent on the coast in SA, it is very grainy but generally putts well.
The other notable feature in Humewood was the general lack of rough around the greens, in particular the elevated greens, the ball tended to run a long way from the hole on misjudged approaches.
Philip, I'm in SA for the good weather,it's been dreadful at home recently, gotta follow the sun.
I watched Imellman on the range a few times,was tempted to put the house on him, lucky I didn't, Ernie played very well.
