Stoneham is a gem. How much of it is surviving Park work I cannot say, but it is a cracker of a course. It's in the northern suburbs of Southampton and makes excellent use of a rolling site. There are some wicked green sites. I wish I had some photos to share with you, but the only time I played it it was miserable weather. Yet it remains firmly etched in the mind.
Aldeburgh is a magnificent course, with brilliantly drained land, the course playing fast and firm all year round. It is perhaps at its best in winter - in summer it can get too dry. There are many gorse-lined fairways, a high proportion of long two-shot holes (no par 5s), some wicked bunkering, and the club guide says that the present course is little altered from that 'suggested by' Taylor and Park. I don't recall that there are any Taylor mounds as at Royal Mid-Surrey. I posted some pictures of Aldeburgh in the British Courses series if someone can scroll back far enough or get the search engine to oblige.
You see Knebworth from the train on the King's Cross line. From there it appears to be a rectangular site with a lot of parallel holes and valleys/gullies crossing at 90-degrees to the line of the shot. I played it once in about 1971 or 2 and I remember nothing about it. That doesn't mean it was good, bad or indifferent, merely that it made no impresion on me at the time.
